I believe that this exercise will be very beneficial to you. I see many beginner jazz students that can play jazz voicings fluently, but only if it is a ii-V-I chord progression. So when I ask a student to play a Bb7 rootless voicing, first he looks for an Fm7 chord and then moves one finger to play the correct Bb7. In other words, he can only play dominant chords (V7) if he relies on muscle memory that’s gets triggered in a context of a ii-V-I chord progression.
This is why this exercise is so important. You can only play this exercise correctly if you know what you are doing. It will make you learn where is the b7th 3rd and 13th of every single dominant chord.
Made with love,
