What makes it tricky
D major has two sharps, F sharp and C sharp. The left hand goes very low, down to low D (D2) on a ledger line below the bass clef. The right hand spans almost two octaves across the variations.
How to practice it
- Pick Left hand at 75% and play the bass loop until your hand knows it. It repeats through the whole piece.
- Pick Right hand at 50% and learn one variation at a time, each a few bars long.
- Pick Both at 50%. Since the left hand repeats, let it run on autopilot and give your attention to the right hand.
