Once a dancer has mastered a repertoire of basic dance moves, expert performance is about working out the choreography for each particular dance piece…
… connecting each individual motion into a seamless, integrated whole.
The same is true with the piano. Once you have a basic understanding of piano technique, the challenge is to understand the unique choreography required of a particular piece of music.
Think of the technical aspect of performance as dancing with a partner (the piano) and you are off to a great start!
