Keling, kuyni birma-bir tuzamiz, uni [] massiviga qo’shamiz, 
davomiyligi [] qatoriga nota muddatlari ro’yxatini qo’shamiz.
Ma’lumotlarni yozuvlar belgisi bilan [] qatoriga, 
mos yozuvlar uchun chastotalar bilan 
ma’lumotlarni esa [] qatoriga joylashtiramiz. 
// MELODIYA - notalar qatori va muddatlar qatori
