To add to this, the W/H sounds great over diminished chords that are not functioning as a "dominant" sound! So, you could use it over a Idim7 chord for example.
@vascofinuras Analyze, W/H from C: C D Eb F Gb G# A B ... so it sounds like a Cdim7 chord. That's the "pure" diminished scale sound. The important notes here are C Eb Gb and A (actually it's Bbb) https://t.co/nCAi4nIHML
@vascofinuras Well ... with the H/W ... you get the root of the chord, then the b9, then the #9, then the 3rd. It's hard to beat that! And on top, you get the natural 13th, and even the #4 ... so it fully describes the dominant chord. On the other hand, start with W, you miss all the alt stuff
