Yesterday I had the rare experience of playing the Mozart Quintet for Four Winds and Piano, K. 452, together with three expert woodwind players--all of us playing the work for the first time with a natural horn. It was astounding to hear everyone respond to the surprising colors of the horn. These are players who know every note of this work, not only their parts but everyone else's as well.

It completely changed the work for them. The drama was inside of the sound, which is where I have always thought it should be.
