So, remember this?
I took another look at it and... Ding! Ding! Ding!!! The light went on. Oh, in the first one, the major 7th is of course the B, then the D is the 9th, and the augmented 11th is the F#. Well, now the chords make sense. Other than the "cluster", which seems to be just a bunch of notes within the scale. Honestly, some of these chords do not sound so great on their own. But that's jazz!
Other than review, taking a look at Dorian scales, blues piano and brushing up on technique have been on my agenda. Progress is coming along. The next step is the exercises prescribed... Arranging.
Wish me luck!
