Text: There are two kinds of progression, melodic or harmonic. Speaking in general terms, the former is a "succession of sounds forming a tune or melody" but the term is also applied to an "imitative succession of melodic phrases" that is to a melodic sequence. Harmonic progression is "the movement of one chord to another" and is diatonic or chromatic. The term is also sometimes used as synonymous with sequence.
