As performers, we must make sure that the right hand is clearly heard through the fifth and sixth lines of the piece. It is the right hand that makes the return of the opening so fresh and exciting. And now we go off on our vacation, disappearing into the distance. Having reached the peak of excitement, we finally relax. The changes in the music become very few and very familiar.
Time slows down.
The b, which was the last important new element to be added, just stays on and on, right out to the end of the piece. We are so familiar with it that it doesn't disturb us at all when it lingers on in the middle of the A major chord at the close of the piece. This is the way a composer makes a piece. He thinks about what he has to say and how he can shape time with sounds to say it. He starts with a sound, any sound, and then makes a different sound, a lot different or a little different, as he wishes.
