Have you mastered your Power Scales (12345)? They’re short, they are part of what you already know (major and minor scales). It pays to put in some quantity/quality to make them very fluent under your fingers – they are going to show up in music a lot more frequently than octave scales (or two- or three- octave scales, which don’t show up at all in compositions).
Here’s the challenge: play through all PS’s up and down (1 2 3 4 5 4 3 2 1) in all keys, any articulation, your choice of register, through the cycle (which I hope you have memorized by now: C F Bb Eb Ab Db F# B E A D G). If you nick a note or otherwise make any mistake, you must repeat that particular PS until you get it right (you are on your honor to be honest here).
