The row has four basic forms: Prime (P): the original ordered set…

To follow up on pitch-class sets, previously talked about in Part 1: First, a clarification that may help you to better understand inversions of pitch-class sets in general. The easiest way to visualize the inversion of a pitch-class set is to start with the top pitch-class member (right-most) of the pitch-class set, and working your…
