(dance) ABA is an extension of the AB structure. After the B phrase, the piece returns to an altered version of the A phrase. The second A phrase can be manipulated by changing the tempo, size, rhythm, or the quality of the movement or by fragmenting, repeating, or changing the order of the sequence.(music) same as dance, but "phrase" refers to musical phrase rather than a movement phrase. The second A is also often varied in music, but the variation is not often a rhythm or tempo variation, but rather a variation at the end of the second A phrase to create a cadence.
