Those nice chaps at sax.co.uk just sent me their newsletter which included the following excerpt from Mornington Lockett's blog in response to a question that was raised following his recent Masterclass at Foyles. I'm sure they won't mind me sharing this with you.
The "10 scale system" evolved over a period of time. The original idea came from a scale I hit upon for a 13th chord with a flattened 9th. I took the Lydian Dominant scale and raised the tonic note by a semitone, thus omitting the tonic from the scale.
This gave the interesting prospect of G7 without a G, leaving more possibilities for variation, and breaking the 'closed system' of fixed scale types to fit chord types.
By changing the notes one by one, I managed to 'migrate' from the Lydian Dominant to the opposite tritone pole, the Altered Seventh. By working with Hexatonic triad pairings, I found I got great results, hopping from one scale to the other.
Scale 1 of the system is the regular Lydian Dominant.
For G7(starting on the 13th): {E,F,G,A,B,C#,D}
Scale 2 is {E,F,G#,A,B,C#,D}
The next step was to add a sharp 5:
Scale 3 is {E,F,G#,A,B,C#,D#}
The next step was to raise the 4th of this scale i.e. add a flat 9 to the G7
Scale 4 is {E,F,G#,A#,B,C#,D#}
Raising the F to F double sharp (G!) gives G# harmonic minor over G7
Scale 5 is {E,F double sharp,G#,A#,B,C#,D#}
Raising the E to E# completes the 'migration' to a tritone away: G# melodic minor, the 'Altered 7th'
Scale 6 is {E#,F double sharp,G#,A#,B,C#,D#}
To get the other 4 scales, you move gradually back to the original scale in the same way:
Scale 7 is {Bb,Cb,D,Eb,F,G,Ab}
Scale 8 is {Bb,Cb,D,Eb,F,G,A}
Scale 9 is {Bb,Cb,D,E,F,G,A}
Scale 10 is {Bb,C#,D,E,F,G,A}
Scale 1 is {E,F,G,A,B,C#,D}
I am having a lot of fun with this, even experimenting with other contexts where the melodic minor would normally be used. In the key discussed, D melodic minor would fit B minor7b5, D minor(6), F major7(Lydian or #5). For example Scale 2 seems to work very well in this way. I think you have to use your ears and your musical brain to decide how far to take it. Mathematical ideas (i.e. set theory) in music provide a fascinating starting point, but you need a strong, intuitive human element for the end result to be any good for me.
Who said jazz was complex. 🙂
