How to practise it

• Listen first: the site plays it while the score scrolls.
• Wait mode: the score waits for you at every note, at your own pace.
• Tempo challenge: play in time, with a score and a map of the bars you got right.
• Find the main motif and follow it from hand to hand; every entry of the theme should be heard clearly. Key signature with 4 flats: name them aloud before playing and spot the places where accidentals cancel them. Fast writing: work section by section in Wait mode, then in dotted rhythms, and raise the tempo in steps of 5–10%.
