New Drills cont.

I got rather compulsive about the arpeggio drill. It consists of taking a note (in my case, C seemed like a good choice), and doing (1) the triad from that root, (2) the triad of which that note is the major 3rd (in this case the first inversion of the A flat triad), (3) the triad of which that note is the minor 3rd (in this case the first inversion of the A minor triad), (4) the triad of which C is the 5th (F, 2nd inversion), (4) the minor triad of which C is the 5th (f, 2nd inversion), (5) the C triad plus the 7th (and my book calls these "major-minor 7ths" - - I think people call them the dominant 7th, in other words a minor 3rd up from the 5th, or B flat), (5) the 7th of A flat starting with C, (6) the 7th of F starting with C, and (7) the 7th of which C is the 7th, or D's. Repeat C and c, then c dim and c augmented, then C one last time. Then I went on to D and did the same - - which took me thru D, E, F#, A flat, and B flat. And then I thought maybe I was done. But that seemed too good to be true. So I charted exactly which arpeggios this much of the drill covers, and it turns out that it's exactly half of the 7 x 13 possibilities. It looks like if I take a half-step after the B flat round and continue with B, then C#, E flat, F, etc., I'll hit them all.
