My piano teacher liked to say
there were four ways to study piano music:
at the piano, with the score
at the piano, without the score
away from the piano, with the score and
away from the piano, without the score   

being lazy, the last was my favorite, though
I often thought she missed the fifth and
most important way to study music:
by loving, losing, living,
my fingers finding symphonies
hidden in your face, your body, your sex
