Here is a run that uses 3 scales.
F Phrygian
F, Gb, Ab, Bb, C, Db, Eb, F
C# Locrian
C#, D, E, F#, G, A, B, C#
G Locrian
G, Ab, Bb, C, Db, Eb, F, G
Now you combine them to form this:
Bb, Ab, Gb, F, Gb, Ab, Bb, C, Db, Eb, F, Eb
C#, D, E, F#, G, A, B, C#, B, A
G, Ab, Bb, C, Db, Eb, F, G, Ab, Bb
You can play it with these chords in the left hand:
Key Db:
bass \ left \ right
Bb, Ab, Gb,
Eb \ Db-F-Gb-Bb \ F, Gb, Ab, Bb, C, Db, Eb, F, Eb, C#
A \ D-F#-G-B \ D, E, F#, G, A, B, C#, B, A, G
F \ Eb-G-Ab-C \ Ab, Bb, C, Db, Eb, F, G, Ab, Bb
Bb \ F-Ab-Bb-D \ (still holding the Bb)
D \ F-Ab-B-D \ (still holding the Bb)
Practice the Phrygian and Locrian in all the keys. You can stick scales in from other keys easily.
