Melodic Minor "Digital" ii-V7-I Exercise
The difference here is that:
1) this one focuses on "digital patterns" starting on the 3rd degree of the Melodic Minor scale (scale steps 3-4-5-7 / 6-7-8-4; ie. F#-7b5 = A Melodic Minor = C-D-E-G# / F#-G#-A-D), and
2) as a ii-V7-I, the pattern transposes up exactly a minor third from the ii7 to the V7 chord (B7alt = C Melodic Minor = Eb-F-G-B / A-B-C-F. It should be noted that the order of the two 4 note cells can be reversed with no change in effect (A-B-C-F / Eb-F-G-B).
This is a nifty little device, which if not overused, can be quite effective over a ii-V. It is also a good sounding "altered" alternative to your typical Major Scale ii-V7 melodic patterns.
