Allan Holdsworth’s 10 Most Usable Scales for 4-String Bass

In 1992, REH released a video for Allan Holdsworth. In it, he gave a little glimpse of his process. His way of displaying and treating scales was of paramount importance.

Included with each of the scale diagrams is a list of the Common Chords which can be derived from that scale.

This article is a work in progress and this topic deserves much expansion, which will be implemented gradually. For the time being, please enjoy this initial listing!
