I was surfing the website of David Valdez and came across the tributes to and Ph.D about the American jazz educator Charlie Banacos. This man was a very significant figure and worth investigating if like me, you are unaware of his work (see CasaValdez for more information)… Just for starters some of the saying attributed to him:
“If you play with your fingers, you’re dead”
“The fingers are passive”
“The body doesn’t want to stop”
“The body doesn’t like angles”
“Row the boat”
“You feel like a diver by the side of a pool, ready to jump”
“Play with your arms, not your fingers”
“Of course it’s difficult; that’s why they call it an etude”
“Ear training—it’s Zen, not Aristotelian”
“Gain purchase”
“Don’t measure” (as you practice ear training—hear it all at once)
“Piano technique—it’s Aristotelian, not Zen”
“Each note has its own shape as it goes by, like you’re driving by the planets”
“Keep your fingers near the keys, and don’t be afraid to raise your wrist”
“Don’t change the exercises”
“It’s a coordination problem”
“Just because you don’t speak like MLK doesn’t mean you shouldn’t talk”
“Think of the numbers, not hand positions”
“Circles, Squares, Triangles -separate them” i.e. one idea after the next, not on top”
“Plan your practicing, or you will be overwhelmed”
“Use all the tensions on the lines; use all the figurations for each voicing”
“It doesn’t matter what finger you use”
“Think like a drummer, using space and range”
“Close your eyes and sit in the audience watching and listening”
“Re: sight reading—it’s a craft, not an art”
“Oh, and do it in all twelve keys.” Kill!
“Divisive rhythm/additive rhythm”
“Elephant with a stick in his trunk” (using it as a guide as you walk/play).
“He’s [insert name here e.g. Mingus, Jerry B. etc.] whacked, but he can play”
“Deep into the keys” (toward the center of the earth and toward the fallboard)

Apparently, he also would stress the following…
