Playin' the Angles!
An Angular, Intervallic ii-V7-I Line
The line's angularity is due to the absence of any consecutive 2nds (Maj. or min.), with the bulk of its interval content being comprised of different qualities of 3rds and 4ths.
This, however, is not a line built on a four or five note scale. Rather, the ii chord contains 6 out of the 7 diatonic note choices from the dorian mode, while the V7 contains all 7 from Melodic Minor (altered scale).
One of the beauties of this line lies in observing how, while moving from the ii to the V7, the scale tones become altered on the dominant side, while the integrity of its shape remains intact.
