blues. These forms divide into sections, each of which will each be given identifying letter names like “A” and
“B.”
Binary Form: Two-part Form
Binary form consists of two sections of similar lengths which repeat.
The melodic material in the B section may be similar to that of the A section, but the key in the B section may
change to a related key, such as the dominant. For a piece in a minor key, the B section may change to the
relative major. This key change, called a modulation, occurs without a change in key signature. The composition
will return to the tonic key before the end of the piece.
