Heptatonic Scales with a 4-Semitone Maximum

This page is derived from Allan Holdsworth's main criterion of a 4-semitone maximum for 'usable scales', applied to seven-note scales.

Holdsworth chose to discard all scales that had more than 4 semitones in a row. He mentioned this in his 1992 REH video where he said:

"And then I catalogued them and filed them away and threw away all the ones that had more than four semitones in a row."

We can also hear him talking about this in the extremely interesting September 2014 Meet & Greet, Part 1.
