A Dictionary of Music and Musicians/Progression

PROGRESSION is motion from note to note, or from chord to chord. The term is sometimes used to define the general aspect of a more or less extended group of such motions. It is also used of a group of modulations, with reference to the order of their succession. The expression 'progression of parts' is used with special reference to their relative motion in respect of one another, and of the laws to which such relative motion is subject. [See Motion.]
