Stay in the key of C
Use the sustain pedal
Only play slow bass notes in left hand
Never obtain a piano made of hammers-hitting-strings
Keep playing that music you already know how to play
Don’t slow down if you make mistakes
…might state the obvious, to get good is to be the opposite.
I worked with an inspiring pianist who’s body language was the opposite of mine. I squirm and contort. My legs and torso move in different directions and my head flings back and I close my eyes. I make weird sounds and I don’t mind any of this, I’m used to trying to not get in the way of what my body wants to do. It has it’s own instincts and I like the results.
But this other person was totally still. Feet still, spine erect, voice silent, eyes open. Sometimes when I was alone I imitated it and I had a completely new experience on the piano. I bet other people find it valuable to track whatever your body already does and then try to interfere with it, privately to see if anything is different in the music experience.
people in concert play a “wrong” not while improvising or soloing, then a couple instant thoughts usually go through the brain.
one is to correct the note but then you are confirming for the listeners that you made mistake.
two is to play the bum note again 200 more times as if to say i did it on purpose and insinuate the listener was at fault for assuming that first time was a mistake. (very clever)
a third choice is to not give a shit about being judged (by yourself or the audience), (who’s response ultimately is just in your imagination).
