Noctave
The piece
This rondo is the last movement of the Sonata in A major, K. 331, whose first movement is a theme with variations. Mozart marked it Alla turca: it imitates the military bands of the Ottoman Janissaries, fashionable in Vienna at the time, with their cymbals and drums. Noctave's easy version takes the refrain in A minor, from the opening motif to the cadence, and simplifies the accompaniment.
Everything grows from a little turn of four eighths, B–A–G-sharp–A, which comes back twice, one step higher each time: D–C–B–C, then F–E–D-sharp–E, before running up to the high A. These groups should be even and light, with the hand close to the keys; the G-sharp and D-sharp mean aiming for black keys without breaking the flow. Soon after, the right hand reaches the high C on the second ledger line above the staff, so read those lines before you play. The left hand alternates a bass note and a two-note chord in half notes; keep it discreet, soft as the score marks it, so the eighths can sing.
