(b) Free fantasies and other improvised pieces and passages.
By the Classical era solo improvisation was carried out mostly by keyboard players, and few excelled at it. Dittersdorf declared that he liked hearing only ‘Mozart, Clementi and other creative geniuses’, whose improvisation had been incompetently aped everywhere. The free fantasy occupies the final section of C.P.E. Bach's treatise. He made it clear that the key to successful improvisations of this kind is a solid knowledge of progressions and consistency of harmonic rhythm. The ametrical fantasy that illustrates his points recalls many of his compositions.
Mozart's and Beethoven's improvisatory abilities were celebrated; their concerts frequently featured solo improvisation. The fantasias composed by Mozart, which may represent revisions of pieces improvised in concert, are mostly metrical; despite their free declamation, they give the appearance of having been carefully worked out. In addition to such fantasies the most common types of keyboard improvisation were spontaneous variations on a given theme, and improvised preludes used either to try out an unfamiliar instrument before a formal performance or to link works in different keys. A number of Mozart's modulating preludes survive. These little-known works (all published in NMA) are mostly ametrical. Beethoven's Fantasia op.77 (which may be a revision of an improvisation at his Akademie at the Theater an der Wien on 22 December 1808) is primarily metrical, though it contains several striking ametrical passages. Schubert's fantasies are metrical.
Keyboard improvisation was not limited to solo performances. Walther Dürr suggested that the lack of piano introductions to many of Schubert's songs implies that the accompanist improvised a brief Vorspiel. Dürr theorized that many of the piano introductions in the posthumous lieder that are not known definitely to have been composed by Schubert were derived from his improvisations; Dürr characterized these not as forgeries (‘Fälschungen’) but as necessary complements (‘Ergänzungen’) to the text in a printed edition for dilettantes.
(c) Continuo in piano concertos.
There is considerable evidence that Classical composers expected the soloist to improvise from the bass – figured or unfigured – during the orchestral ritornellos of keyboard concertos. 18th-century published editions of the keyboard part usually contain a figured bass in those sections, and Mozart notated ‘col Basso’ (‘with the bass’) in the left-hand staff of the keyboard part on virtually every page of the score where the soloist does not have an obbligato part. The reasons for this practice are still debated. Such concertos were normally conducted from the keyboard; it has been argued that the keyboard played chords to keep the orchestra together or that the bass line was nothing more than a cue to prevent the soloist from getting lost.
The Badura-Skodas (pp.207–8), pointing out the obvious differences in timbre between fortepiano and modern piano and between Classical and modern orchestral instruments, adduced criteria for the discreet use of continuo in modern performance. Neumann (1986, p.255) was more categorical, rejecting its use except on old instruments, and Charles Rosen (2/1972, p.192) stated flatly, ‘In the concertos of Mozart there is absolutely no place where an extra note is needed to fill in the harmony’. Two documents pertinent to the controversy survive. The first is an autograph continuo part of Mozart's Piano Concerto in C k246. The Badura-Skodas and Szász argued that it shows how Mozart played continuo. The second is the carefully notated continuo part in the autograph to Beethoven's Fifth Piano Concerto op.73. The lack of similar explicit directions in the earlier keyboard concertos can be explained by the fact that Beethoven personally performed them; the fifth was the only one he never played. The continuo part contains scrupulous figuration and indications of tasto solo, a l'ottava and Telemann-Bögen, and occasionally doubles the bass in octaves. Even if these annotations served a purely pedagogical purpose as part of Beethoven's instruction of Archduke Rudolph, as argued by H.-W. Küthen in his edition, it seems unlikely that Beethoven would use the manuscript of one of his most important works merely to teach an art which had no practical use. Beside the debate about the applicability of continuo in Classical concertos lies the question of how it was played. Some present-day scholars consider continuo to be a purely functional element of 18th-century music: the player merely plays a chord at each change of harmony, so as to complete the texture and keep the orchestra together. However, purely chordal continuo playing would contradict both the tradition of thoroughbass and the treatises of the period. Quantz and C.P.E. Bach specifically suggested that the continuo player vary the number of upper voices and improvise linear and quasi-linear music when appropriate. All thoroughbass textbooks treat voice-leading as primary, dealing not merely with the interpretation of the figures but with their contrapuntal implications. It would be as fallacious for the Classical period as for the Baroque to assume a composer to be unconcerned with a chord's qualitative presence merely because it was not written down. Notated accompaniments were unnecessary because players were able to improvise them.
Improvisation, §II, 4: Western art music: The Classical period
(ii) Vocal music.
Instructional and theoretical works came, through their sheer quantity, to assume a new importance to the student of ornamentation as the Classical period began and music publishing flourished. Some 20 comprehensive vocal methods or critical studies appeared in the period between 1763 and 1825 (after which the Rossinian revolution begins to be reflected). Many contain extensive notated examples, and these are of especial value in a period both of operatic reform and of virtuoso vocalism. The latter was cultivated with care, ambition and respect, although its extreme manifestations found cogent and persuasive detractors. Most writers on the subject discuss questions of taste and judgment, balancing the claims of composer and virtuoso; there is much thoughtful argument, and subtle differences of emphasis are found between writers. But without matching such accounts to detailed, notated examples it is impossible to determine what might have sounded restrained and what daring, still more to establish what were considered the idiomatic ways of carrying out standard ornamental procedures.
Domenico Corri is probably the most valuable single theorist as far as the provision of practical examples is concerned: he printed details of execution that were normally left unwritten, over a wide range of music; he was more reporter than advocate; and he was respected by his contemporaries. Other important writers were Giambattista Mancini, J.A. Hiller, J.B. Lasser, A.M. Pellegrini Celoni, J.F. Schubert, Giuseppe Lanza, Alexis de Garaudé, G.G. Ferrari, J.B. Rocourt, Isaac Nathan and R.M. Bacon. Annotated performance materials are plentiful but not readily accessible for study; in London, following Corri’s lead, publishers began to issue arias with embellishments and nuances indicated by small note heads, and there and in Paris arias were published showing a particular performer’s ‘realizations’ on a separate staff.
Little or no ornamentation is advised for plain recitative; Hiller (1780) stated that ornaments should be confined to occasional mordents and Pralltriller, though he accepted the need for more in scenas in accompanied recitative. J.F. Schubert advocated ‘appropriate free embellishment’ for fermatas but cautioned that this should be avoided where the word to which it would be sung made it inappropriate. In slow arias, or the slower sections of two-part rondò arias, the use of portamento was advocated by Corri, with messa di voce on longer notes, and the line might be highly graced, with appoggiaturas (single or compound) and acciaccaturas as the most common ornaments; little running passages might bridge leaps or fill out long notes, and syncopation, echo effects and division-like passages might be used. The surviving examples embellished by Mozart show the use of such devices (ex.21). Allegro arias or sections were less subject to decorative ornament, largely because of their greater speed and stricter tempo. Passing notes, appoggiaturas and the like are found, but in less profusion, and unmeasured flurries of quick notes are rare. Staccato and syncopation are sometimes used as ornamental devices, and running passages of semiquavers may be constructed on the outlines of melodies in longer note values. Hiller (1780) explained the distinction: ‘in slow and pathetic arias, slurred and drawn-out ornaments are the most appropriate, just as thrusting ones belong more to the Allegro’. In both styles, ornamentation generally involves adding notes of quicker rhythmic denomination rather than rerouting existing semiquavers into another region of the voice or simply recomposing the melodies (a practice often followed in modern revivals). Some degree of thematic variation, however, was expected in the case of an aria with a recurring theme as it reappeared.
Many complete arias survive with ornamentation attributable to specific composers or singers. The Czech composer Václav Pichl noted, in Milan in 1792, the variants sung by Luigi Marchesi in different performances of Zingarelli’s Pirro (ex.22); its opening line gives some indication of what theorists meant when they decried ornamentation that overwhelmed the original. At least eight examples were published of the decorations sung by Angelica Catalani, which were equally florid. Mozart’s preferred style of ornamentation, ascertainable from ex.21 and from his elaboration of an aria from his Lucio Silla (1772), shows a number of features: (a) the use of passing notes and other small ornaments in the first statement, increased in the repeat; (b) the standard use of appoggiaturas on feminine line endings (and often elsewhere; the speed of their resolution should be noted); (c) the variety of pace in the passage-work, with the prevailing semiquavers often enlivened by a burst of demisemiquavers or uneven groups of quick notes; (d) the tendency to use embellishment to increase the complexity and speed of figuration (as opposed to altering melodic shape or tessitura: the idea of adding ‘excitement’ through high notes seems to play no part); (e) the use of syncopation and phrasing to vary the line, and (f) the increase in elaboration as cadences are approached. In the Lucio Silla aria it is worth noting, additionally, that the wide leaps in long notes are left unornamented.
Several theorists stress the importance of exactitude and curtailment of liberties when two or more voices are singing together. Pellegrini Celoni wrote:
Duets, trios, quartets etc. must be sung as they are written, and though it is permissible to vary this or that in the solos, in the remainder it is necessary to proceed with unanimity, and to pay close attention to forte, piano and pianissimo; to smooth out, connect and separate … in concerted pieces, … appoggiaturas, trills and mordents are still permitted, but always with moderation.
Others emphasized that cadenzas for two voices or for voice with obbligato instrument (which was expected when the accompaniment featured one) must be prepared in advance and were often written out by composers. Many examples survive, among them several for the duet for Susanna and Countess Almaviva in Le nozze di Figaro and for ‘Ah perdona’ from La clemenza di Tito.
Most of the foregoing discussion applies primarily to Italian music. Outside the Italian sphere, the application of italianate style decreased in proportion to the distance of the music itself from Italian models. Germans noted approvingly (and Italians complainingly) that sophisticated German accompaniments made vocal freedom and ornamentation less appropriate. J.F. Schubert admonished that the ‘compositions of Mozart, Haydn, Cherubini and Winter will bear fewer embellishments than those of Salieri, Cimarosa, Martín and Paisiello’. French singers seem to have carried from earlier generations some of their system of well-defined and differentiated ornaments which they preferred to the bolder manifestations of italianate passage-work, and to have applied them quite liberally to the ariettes and the strophic songs in their operas. In one kind of English song, where the voice moves predominantly in octaves with the bass, it is implied by Corri that the voice did not normally break the unison to add ornamentation; the basic shape of the vocal melody is retained, but passing notes and other smaller graces might be added. These, along with the gruppetto, or turn, and portamento, seem to have been regarded more as a part of tasteful execution than as ornamentation.

Improvisation, §II, 5: Western art music: The 19th century
(i) Instrumental music.
The early 19th century witnessed a meteoric rise in the popularity of improvisation and then its near-extinction post-1840 after suffering an ‘apotheosis of bad taste’ (Wangermée, 1950). The Romantic mind revelled in the spontaneous creativity of improvisation and its unique incarnation of musical genius. But improvisation also served more prosaic ends by pandering to a music-consuming bourgeoisie that craved brilliance and sensation, thus encouraging its rapid decline as trivialization threatened the artistic originality that had distinguished it in its 18th-century heyday. Other factors leading to the eradication of public improvisation included the rise of the performer as interpreter and the divorcing of composition from performance; the concomitant ascendancy of the ‘work concept’, itself inimical to the notion of music in flux so vital to improvisation; and an evolution in musical technique away from bass-orientated, syntactical structural outlines towards more melodically, generically or programmatically conceived frameworks which loosened the ‘inner thread’ (Schumann, 1854) that previously had held much extemporized music together.
In the first decades of the century, however, improvisation claimed a central role within musical culture – thanks to the pre-eminence of the piano, the instrument on which it was most commonly practised. Advances in design and construction thrust the piano on to centre stage in the concert halls of increasing importance in the era; greater virtuosity and expressivity resulted in particular from the instrument's enhanced sustaining powers, enriched timbral palette and repetition action (patented 1821). These were ruthlessly exploited by the ‘lions of the keyboard’ touring Europe, who inevitably included at least one improvisation in their concert programmes. Generally the last item to be heard, such an improvisation often featured popular melodies or operatic airs. Masters like Hummel and Liszt improvised on themes provided by the audience, partly to counter critics' charges that extempore performance was ‘little more than playing from memory’ (The Harmonicon, June 1830). Even Chopin – whose improvisations on Polish national melodies charmed audiences in Warsaw, Vienna and Paris – used this trick on occasion, once to please three clamouring princesses typical of the more private salon audiences, or Damenwelt (Moscheles, 1872), for whom improvisation was also de rigueur.
Another celebrated improviser was Beethoven, whose extemporizations, according to Czermy, were ‘brilliant and astonishing in the extreme’, ‘whether on a theme of his own choosing or on a suggested theme’ (ed. P. Badura-Skoda, 1963, trans. 1970). They generally took ‘the form of a first movement or rondo finale of a sonata’, a ‘free variation form’ or ‘a mixed form, one idea following the other as in a potpourri’ – formal procedures laid down in Czerny's own Systematische Anleitung zum Fantasieren auf dem Pianoforte (1829), perhaps the most important (certainly the most informative) improvisation treatise from the period. Others were published by the likes of Corri, Hummel and Kalkbrenner for the benefit of less skilled professionals and ‘conscientious amateurs’ (Kalkbrenner, 1849).
Czerny's treatise elucidates in turn the improvisation of preludes, cadenzas, fermatas and independent ‘works’ (fantasies, potpourris, capriccios etc.) but says little about their common characteristics. Dahlhaus (1979) argued that any improvisation – by definition spontaneous, though not necessarily original – involves the realization of one or more ‘models’, however defined. In the early 19th century, such models included chromatic bass progressions, discursive ‘nocturne’ accompaniments (usually supporting stylized vocal figuration), and harmonic sequences embellished by chord-outlining passage-work (arpeggios, scales, Rollfiguren etc.), all of which the hands might execute ‘almost without any consciousness of the mechanical operations which they perform’ (Hummel, 1881). Czerny too noted that the improviser frequently succumbs to ‘an almost subconscious and dream-like playing motion of the fingers' while nevertheless ‘adhering constantly to his plan’ (1829, trans. 1983; compare Fétis and Moscheles, 1840).
As Czerny indicated, improvisers also utilized higher-order plans refined through practice and experience to lend coherence to their extemporizing. In contrast to the simple figured-bass ‘skeletons’ (Gerippen) exemplified in C.P.E. Bach's Versuch, larger-scale improvisatory models after 1800 often comprised loose formal templates defined in thematic terms. The prevailing stile brillante offered a ready-made paradigm with its characteristic alternation between virtuoso and lyrical episodes, an approach also taken in countless ‘brilliant’ compositions by Hummel, Chopin, Liszt and lesser contemporaries. The cement binding successive phases of the occasionally sprawling improvisations that resulted from this and similar formal strategies was melodic and motivic ‘imitation’ – ‘a study of the utmost importance to a pianiste who is desirous of extemporizing’ (Kalkbrenner, 1849). Ironically, the requirement of ever-greater organic unity in improvisation hastened its demise by inhibiting an essential freedom (Dahlhaus, 1979).
Czerny insisted, however, that an improvisation, although ‘in a much freer form than a written work’, ‘must be fashioned into an organized totality as far as is necessary to remain comprehensible and interesting’ (1829, trans. 1983). Improvisations on a single theme were ‘the most difficult of all’ but could be crafted in an ‘interesting and orderly fashion’ simply by combining ‘several styles into one and the same fantasy’ (for instance, ‘Allegro’, ‘Adagio or Andantino’, ‘fugal’, ‘modulatory’, ‘lively rondo’) while avoiding ‘an eternal, wearisome, continuous repetition of the theme through all octave ranges and an irrational journeying back and forth among the keys’. A somewhat freer fantasy could be devised with several themes (the first – ‘the pillar on which all else is constructed’ – must ‘recur frequently between the remaining themes’ and again at the end); as a potpourri (a ‘combination of such themes that are already favorites of the public’); or as a capriccio (‘an arbitrary linking of individual ideas without any particular development’). Other possibilities included theme-and-variation and ‘strict, fugal’ formats.
Preludes had more practical functions than the fantasy, among others to test the instrument, establish an appropriate mood and warm up the fingers. Although mostly ‘introductory’, preludes were also improvised as links between pieces, a practice resurrected on occasion long after the demise of preluding mid-century. Typically restricted in motif and harmony, preludes might commence in a remote key but normally ended on the dominant 7th chord of the main tonality, thus resolving to the ensuing composition. Stylistic possibilities ranged from unmeasured recitative to bravura virtuosity, as demonstrated in the numerous collections published from 1810 to 1830 for both professionals and amateurs (e.g. by Hummel, Cramer, Haslinger, Moscheles and Kalkbrenner).
Recitative passages also infiltrated period compositions (for instance, Chopin's Nocturne op.32 no.1; Beethoven's Sonatas op.31 no.2, op.110), along with other improvisatory devices like cadenzas (i.e. in solo pieces) and embellishments (often vocally inspired). Ironically, the latter features lost their earlier improvisatory purpose in that cadenzas were increasingly notated by composers in concertos, while improvised embellishments (portamentos, fioriture etc.) came to be viewed as ‘concessions to bad taste’ and ‘sacrilegious violations of the spirit and letter’ of composed music (Liszt, 1837).
As for fantasies committed to paper, these reveal the evolution in the models used by improvisers even if they lack the spontaneity of live improvisation. Although dubbed a capriccio by Czerny, Beethoven's Fantasia op.77 (published 1810) amounts to a ‘Fantasy-Prelude’ preparing a theme-and-variations set with coda, this formal succession corresponding to a background bass motion (ex.23) from B /A (‘Fantasy-Prelude’) through B (theme and variations) and C (final variation) back to B (coda). This simple turning shape – recalling the structural foundation in Mozart's Fantasiak475 (see Rink, 1993) – may be typical of tonally conceived early 19th-century improvisatory models, likewise the starkly juxtaposed keys (f–f –f) in Schubert's Fantasia for piano duet d940 (1828; ex.24); the extended chain of 3rds (f–A –c–E –G –[B]–G –b –D –f–A ) spanning Chopin's Fantaisie op.49 (1841); and, in Chopin's Polonaise-Fantaisie op.61 (1845–6), the linear bass ascent A –B –C –D –E uniting seemingly disparate thematic and virtuoso episodes (see Rink, 1993). In contrast, Liszt's Réminiscences de Don Juan (1841) derives structural logic through a reordering of Mozart's operatic plot: after a Grave opening intoning the Commendatore's music from Act 2 (D major) follows a lengthy theme-and-variations treatment of ‘Là ci darem la mano’ (A major), then a brilliant finale in B based on ‘Fin ch'han dal vino’ (typical of the ‘rousing, dazzling conclusions’ recommended by Czerny in longer fantasies). Liszt's dramatic conceit – whereby dissolution triumphs over virtue – controls the Fantasy, not an underlying tonal framework inherited from earlier improvisatory traditions. In contrast, his B minor Sonata (quasi una fantasia?) directly exploits tonally defined improvisatory models, a simple key progression b–D–F –b/B stabilizing the alternation between thematic and bravura passages.
The assimilation of improvisatory styles and procedures into formal composition (as shown in Liszt's Sonata) was yet another factor contributing to improvisation's decline, as the bold liberties or ‘stretched conventions’ (Carew, 1981) that once characterized it became compositional norms, thus undermining its special status. Improvisation did not however disappear altogether but became restricted to domains like organ playing, often in the ‘strict, fugal’ style described by Czerny and contemporaries. Thus pursued, its purpose was chiefly academic, although Bruckner's exceptional organ improvisations in concerts in Paris (1869) and London (1871) thrilled audiences.
Though dominated by the solo piano and, later, the organ, 19th-century improvisation was also practised by violin-piano duos (e.g. Clement and Hummel, Reményi and Brahms) and other instrumentalists, while Beethoven and Wölfl, Mendelssohn and Moscheles, and Chopin and Liszt improvised publicly on two pianos.
Improvisation, §II, 5: Western art music: The 19th century
(ii) Vocal music.
Pedagogical sources of the Romantic period tend to concentrate more on technical and physiological matters than on questions of performing practice; but the increasing publication of vocal scores provides a rich surviving body of annotated performance material. By the end of the period a far more specific and illuminating type of evidence is available in the form of sound recordings. Among many informative vocal methods may be singled out those of Lablache (for its brief, intelligent overview of ornamental practices), Duprez (for the new dramatic style and cadenzas), Garcia (the most comprehensive), Faure (valuable for the distinction between French and Italian practices) and Delle Sedie. Sieber, Lemaire and Lavoix, and Bach provided valuable stylistic information with emphasis on practices in their respective countries. There also survive, published and in manuscript, arias ‘realized’ or annotated by Rossini and Donizetti and by (or after) many of the leading singers of the time, as well as isolated ornaments by Verdi and various singers. Additional clues may be obtained from instrumental adaptations or fantasias.
In orchestrally accompanied recitative, cantabile, arioso elements and ornamental vocalization continued to be important; composers increasingly wrote the ornaments into the score. Ex.25 shows part of Tancredi’s opening recitative, as scored and then as realized by Rossini for a singer. Examination of this, along with recitative realizations by Rubini, Garcia and others, shows that the greater floridity and greater variety of note values observed in Verdi’s recitatives reflect an increase not so much in elaborateness of recitative style as in the specificity of notating it – indeed, the elaboration of execution probably decreased somewhat, in contrast to the notational practice.
The ‘aria cantabile’ continued to be the principal locus for melodic embellishment. Garcia, who is more explicit even than Domenico Corri, gives details of phrasing, dynamics and expression as well; ex.26 shows a section from one of his examples. A decrease in density of figuration across the first half of the century is easy to discern; extending the examples backwards to, say, Catalani, at the beginning of the century, and forward to the artists heard on early recordings, would show this to be a steady, continuous process.
The cabaletta, the fast final section of the aria from the time of Rossini until the dissolution of standard aria structures into the more flexible forms of the mature Verdi, consisted of a strophe, a ritornello, an exact repeat (occasionally abbreviated) and a coda whose length and complexity varied considerably. Rossini wrote to Clara Novello that ‘The repeat is made expressly that each singer may vary it, so as best to display his or her peculiar capacities’. The transitional passage from the slow section (sometimes in recitative) often concluded with a vocal flourish, which could recur between the strophes. These flourishes most often expressed a simple, unresolved dominant 7th. Surviving examples include variants by Pauline Viardot (for a pupil) for the lead-in to ‘Sempre libera’ (La traviata) and one in the role-book for Azucena used to launch ‘Deh! rallentate, o barbari’ in the French version of Il trovatore in Paris (1857).
Ornamentation in the cabaletta itself is of three kinds: elaboration of fermatas, most often at the end of each strophe or during the coda; variation of the basic stanza on repetition; and elaboration of the coda’s stock cadential sequences, whose similarity from piece to piece facilitated free improvisation. In contrast to the usual gracings of cantabile, cabaletta repeats took the form of genuine variations, freely altering the melodic shape at times. Orchestral doublings of the melodic line were often removed to facilitate ornamentation, as can be seen from numerous sets of 19th-century parts. Many examples of cabaletta variation (by Jenny Lind, Giuditta Pasta and others) survive; Rossini’s for several of his own cabalettas, and one each by Bellini and Nicolini, were published (with imperfect but decent fidelity) by Ricci.
In Rossini, Bellini and Donizetti, the coda is based on the same chord sequence observed at the end of the cantabile, but in tempo and usually with accelerating harmonic rhythm (ex.27); this portion was elaborately and freely varied. Garcia, Lanza and others give tables showing the multiple possibilities, and examples by Rossini and many singers exist. Cabalettas continued to be embellished in early Verdi (Giulia Grisi’s variations for I due Foscari survive in Rome). By the time he stopped writing them – his last orthodox solo cabaletta is in the 1863 version of La forza del destino – the repeat was commonly omitted in performance. It seems likely that cabalettas were ornamented only as long as they were repeated.
Up to, and probably throughout, Rossini’s time, the end of the coda seems to have been taken without rallentando and with a burst of florid virtuosity, often concluded in the low register. But as the excitement of the held top note gradually assumed a greater role in vocal expression, it became customary to add one just before the final note of the cabaletta while the orchestra pauses or sustains. This is sometimes found in Verdi’s scores, and occasionally earlier, although it became a universal practice only later. Increasingly, towards the end of the century, much or all of the coda was omitted; the singer proceeded from the final fermata of the strophe directly to the last few bars of coda or to the postlude. The conclusions in ex.27 clearly envisage an ending in tempo. Ex.28 shows two more cabaletta conclusions: one by Naldi, clearly ending in tempo, and one by Viardot from about 1880, showing a hold before the final note, now taken in the high register. Many sets of cabaletta variants break off at this point, suggesting a conclusion more or less as in the score or with conventionalized elaboration, and many sources that are specific about accompaniment practice (above all Garcia) show the conclusions of their cabalettas with no hint that the tempo was to be retarded.
It is clear from Rossini’s revisions of his Italian music for Paris that the norm there was less florid than in Italy (despite the fact that the Paris operas were still liberally embellished, as we know from Cinti-Damoreau and numerous other sources). The strong penetration of the Italian repertory in the 1840s and 50s by translated versions of Meyerbeer and Auber (to be followed by Gounod, Thomas and Massenet) led the way towards a simpler style of impassioned lyricism in Italian singing. Nevertheless, it was the French who maintained the old Italian skills of florid singing rigorously to the end of the century, while their Italian contemporaries had long simplified Rossini’s Otello and were beginning to do the same to the less demanding Barbiere. In Germany and eastern Europe, a tension between the dominance of Italians and emerging native styles was felt throughout the century, with the Italians essentially ranged on the side of more freedom for the soloist. By the middle of the century in Germany, and by its end throughout Europe, schools of singers had emerged as specialists in national repertory (eventually in Wagner).
Recordings provide valuable evidence on ornamentation. The first opera singer known to have made a surviving record is Peter Schram (1819–95), who in 1889 sang two excerpts from the role of Leporello into a cylinder machine; although it provides interesting testimony to the transmission of Classical music, the record has little bearing on the performance of Romantic music. Seven singers born in the 1830s, and 24 born in the 1840s, also recorded, as did several dozen born in the 1850s and 60s. This body of evidence brings the priceless opportunity to observe many aspects of vocal technique. Ornamentation was still practised, mostly by Italian singers but also by foreigners who made their careers in Italy or who became part of the budding ‘international’ scene in New York and London, and by some of the more old-fashioned artists based in France and Germany.
The ornaments are simpler and fewer than those in use earlier in the century. Most were staples of ornamental practice going back at least to the Classical period: gruppetti of four or six notes, acciaccaturas, two-note slides, and the accented reiteration of the antepenultimate note of a cadence that Garcia traces back to the castratos and that was popularized by Rubini. These ornaments were all started on the main note, even the acciaccatura: though notated with a single ‘small note’ above the main note, it was uniformly executed as what we would now call an inverted mordent (unless approached by step from below, in which case it was sometimes sung in the ‘modern’ one-note fashion). The only prominent ornament not found in earlier sources, and that seems to have developed in the second half of the century, is the extended acciaccatura figure (ex.27c); this was widely used in Verdi. French singers – less often Germans, almost never Italians – still introduced trills and executed the written ones with great clarity and elegant resolutions.
In early recordings, the preoccupation with interpolated high notes had not reached its peak; singers with good high notes often added them, but many recordings of favourite arias lack the familiar extra high notes. These, like the ‘standard’ coloratura variations of ‘Una voce poco fa’ and the Lucia Mad Scene, are mostly products of the earlier part of the 20th century, when Italian conductors and coaches set about the task of establishing more or less fixed texts for surviving Italian operas from the period of improvisation.
Improvisation, §II: Western art music.
6. The 20th century.
In addition to the continuing traditions of improvisation associated with functional music (e.g. social dance, organ playing in church), the early 20th century added a new kind, that of extempore piano accompaniment to silent films. But of course the richest new manifestation of improvised music was jazz. This had an influence on almost every composer from Debussy onwards, but not as improvisation. The first half of the 20th century was, on the contrary, a time of great emotional exactitude, except in the music of a very few composers, including Ives and Grainger, and even in their scores the performer’s freedom is limited to such matters as choice from among different versions, or how to achieve a compromise with idealistic demands. Composers’ performances of their own music (the recordings made by Stravinsky and Bartók, for example) reveal how much liberty could be taken in practice with music that looks, on paper, to be complete and precise in its requirements, but such liberty did not extend to improvisation. Where the term was used in a title (e.g. that of Bartók’s Improvisation on Hungarian Peasant Songs, 1920), it was to denote an impromptu style in music fully written out.
The lapsing of improvisation is understandable in a musical culture that was rapidly losing those elements of common practice on which improvisation depends: the idea of extemporizing cadenzas to, for example, Schoenberg’s Violin Concerto is almost unthinkable. However, composers who abandoned traditional culture in order to make up their own ways of doing things (e.g. Partch and Cage) found themselves bound to improvise, and sometimes let their performers do so too – although Cage consistently resisted this, and preferred to have his musicians follow exacting rules if not scores. Improvisation, as a spontaneous expression of intention, was just what he wanted to avoid.
Nevertheless, his influence may have contributed to the re-emergence of improvisation in composed music during the 1960s – along with other factors including the growth of live electronic music (and hence of unpredictable situations), the development of jazz to a point where it could embrace almost everything in the contemporary classical tradition (so that the definition of a performance as ‘free jazz’ or, from the classical standpoint, ‘free improvisation’ became arbitrary), the arrival of performers who wanted to go their own ways, composers’ growing knowledge of non-European music, their extension of Aleatory procedures, and a general movement in Western culture towards democratization and universal self-expression. Yet that movement did not extend so far, or for so long. Improvisation was rapidly reaffirmed as secondary to composition, in that improvising artists (except those also known as composers, such as Vinko Globokar, La Monte Young or Terry Riley) gained no broad platform, and composers (Stockhausen, for example) soon retracted the freedom they had permitted. Once the 1960s had passed, the old division between creative and performing musicians was restored.
In the performance of older music, however, that division came increasingly under attack, as musicians pressed forward their efforts at period style. Any attempt to perform, for example, troubadour song demands some contribution from the singer, although this is more likely to be prepared in advance rather than truly improvised. The same is true of ornaments and cadenzas, which gradually, though not everywhere, came to be expected in the performance of 18th-century music. However, some musicians (such as the keyboard player Robert Levin) began in the 1980s to emulate their colleagues of two centuries’ distance in improvising cadenzas and fantasias on the spot. The revival of silent-film accompaniment at the same time might suggest an acceptance, by the musical culture, of improvisation as a reawakened historical phenomenon.
