Are you stuck between studying for tests and logging in much needed time on practicing technique? Try this idea that came up during one of my lessons last week:
This student is working on his Grade 8 piano technique. Four octave scales - woohoo?
He played d harmonic minor for the first octave and d melodic minor for the second by accident. Then, I had him play D major for the first octave, d natural minor for the second octave...you get the idea.
Basically in one pass, you practice all the scales you need to know for a traditional music exam. However, to actually hear any improvement, you'll have to play it this way more than once. More than twice.
You can change things up of course. Try this on all the minors (natural, harmonic, melodic, jazz). Or be bold and try these on some of the jazz scales.
The bottom of the white board refers to an idea I think has already been mentioned. Play the ascending scale one way (e.g., major), and the descending scale another way (e.g. harmonic minor).
You have to be awake to do this kind of practice. Well really, we should be all striving for mindful practice anyway...right?
