The purpose of this downloadable minor ii-V7-i exercise, which utilizes 3 Melodic Minor scales (in directionally alternating diatonic 3rds), is at least three-fold:

1) Because Melodic Minor has no "avoid" notes, one can start and resolve the ii-V7-i cadence on each and any scale degree.

2) To smoothly connect, by whole or half step, from one scale to the next, moving in the same ascending or descending direction.

3) Most importantly, to help train the ear to the sound of Melodic Minor in general and to the sound of this type of polymodal ii-V7-i in particular, as well as to build instrumental technique.
