What songs that have binary form​

Explanation:

A classical piece that uses rounded binary is the 3rd movement from Mo zart's “Piano Sonata in D Major”. The first page of the music (with the two repeated sections) acts as a rounded AABB. Another example is the classic folk song “Oh Susanna”

a chromatic scale uses the twelve tones of the octave, while a regular scale only uses eight, or seven different notes (as the first note is played twice)
