Symmetrical Scales: The Half Whole Diminished Scale
Symmetrical Scales are scales that are marked by interval patterns within one or two octaves. There are four types of Symmetrical scale based around one or more interval patterns repeated in a cycle. They are particularly useful for improvising over extended and altered chords
Half Whole Diminished Scale
The Whole Half Diminished Scale is built by repeating interval patterns of a Half (or semi) Tone followed by a Whole Tone and can be used to solo over a 13b9 chord as well as adding a #9 and a #11. It is constructed as follows:
R b2(b9) b3(#9) 3 #4(#11) 5 6 b7 R
Or in the key of C:
C Db Eb E F# G A Bb C
Make sure that you learn this scale over all 12 keys and in other positions on the guitar to really get it down and then try playing it over a 7th chord to get a feel for the sound of it!
Once you have this scale mastered, pick a standard out of your jazz repertoire and incorporate these in the relevant places to add some colour and diversity to your solos!
