These are good, I like to do all my Major, Minor, Dominant and Half Diminished arps in the circle of fourths going through all 12 keys in three different positions in time.

For instance, C Major Arp- 13579753 is C, E, G, B, D, B, G, E

then go to F Major, Bb Major, Eb Major and so on.

Forwards and backward in time, great exercise!! Especially for Soloing over changes like Jazz, Rock Fusion.

That's my ish!
