 when I was 14 years old and I found it was a wonderful way for me to learn about the flexibility of my hands and my abilities and how to move them in a way that was comfortable in a pianistic way. The opening chords are difficult and they present a challenge immediately in terms of selecting the tempo, making the build up and bringing the inner voices to attention. And in the second bar, a trick that I have for this very big chord, is that I take the C and the D-flat with my thumb. And this takes a specific amount of practice and positioning of the hand, so you have to really angle it towards the thumb.
