About Spinner

Spinner lets composers create, view, transpose, and print musical series—rows of artfully arranged pitches—in any or all of the classic permutations: prime, inversion, retrograde, and retrograde inversion. Creating a series manually is time-consuming; Spinner makes it quick.

A musical series is used in the creation of contemporary music much like the major scale and tonal harmony were used for music of past centuries. See "What's a series?" for more information about series.

Spinner is a native Mac OS X application.
