The Instrument Plays Itself

[I swiped this picture from Dharmadhatu:dharmadhatu]

The quote is from the man who knew so much about joy: J.S.Bach:

There is nothing remarkable about it. All you have to do is hit the right key at the right time and the instrument plays itself.

As one would expect from someone who knows joy, this is about more than eliciting song from a keyboard.
