Approaches to Improvisation

[PMB]

Just 4-note phrases, either diatonic (made up only of scale tones) or non-diatonic (i.e. containing some chromatic notes). Can also be combined in various ways into 8-note phrases (or longer).

I've been taking common cells such as the ones that appear in Randy Vincent's The Cellular Approach book and creating chromatic variations. For instance, the first two shown here are diatonic scale-based and triad-based cells respectively followed by their chromatic correlatives. Each of these cells can then be treated as containing two halves open to recombination.
