In addition to Letters of Note, Lists of Note has some excellent "found" inspiration from time to time. A recent one, from Thelonious Monk:
DON’T PLAY THE PIANO PART, I’M PLAYING THAT. DON’T LISTEN TO ME. I’M SUPPOSED TO BE ACCOMPANYING YOU!
THE INSIDE OF THE TUNE (THE BRIDGE) IS THE PART THAT MAKES THE OUTSIDE SOUND GOOD.
DON’T PLAY EVERYTHING (OR EVERY TIME); LET SOME THINGSGO BY. SOME MUSIC JUST IMAGINED. WHAT YOU DON’T PLAY CAN BE MORE IMPORTANT THAT WHAT YOU DO.
ALWAYS LEAVE THEM WANTING MORE.
