Jazz Piano Brain Teaser #1

Practice this in all keys ( WITHOUT  music, of course - this is jazz!) visualizing the chord name and what degree of the chord is on the bottom and top.   Every other chord is a Cm7(b5) in the same open voicing configuration but different inversion.  Every transition chord is a Ddim7 chord in the same open voicing configuration but a different configuration than the Cm7(b5) chords.   It's a great sounding and useful progression that reminds the brain and the hands to always use good voicings and voice leading while  helping to maintain healthy brain-cells through exercise.   ( accidentals do not carry over;  sorry for the Cb but that is the correct spelling of the 7th in a Ddim7 chord ). If you like this I have lots more.

Alternating Cm7(b5) and Ddim7 Open Voicing Brain Challenge

To help with visualization, imagine the chord in closed position and observe that the Cm7(b5) chords are voiced with the outside ( top and bottom) notes in the left hand and the middle 2 notes are in the right hand.  Imagine the Ddim7 in closed position and observe that the bottom and 3rd notes are in the left hand and the 2nd and top notes are in the right hand.
