and see what you find. Among my favorite sites (as of summer 2005) are Music
Notes Music Theory (library.thinkquest.org/15413/), Teoría Music Theory Web
(www.teoria.com), and Ricci Adams’s Musictheory.net (www.musictheory.net).
While you’re on the Internet, make sure you check out my personal website
(www.molehillgroup.com). There you’ll find information about my latest book
projects and (at www.molehillgroup.com/theory-corrections.htm) any updates or
corrections to the information in this book.
The Internet is also a good way to get in contact with me; my e-mail address is
[e-mail]. I encourage and appreciate any comments you
might have about this book, or about music theory in general; it’s always good
to hear from fellow musicians.
If you love music, as I do, you’ll want to experience as much of it as possible.
The more you play, or sing, or just listen, the more you’ll learn about the theory
behind the music. So put down this book and put on your favorite CD—or pick
up your instrument and start playing. The music is waiting for you!
