Noctave
The piece
The title promises plain-spoken music, and the writing keeps its word: in F major and triple time, a right hand tumbling down sixteenth-note scales over chords held in the left. Burgmüller builds the whole piece on that contrast between a busy right hand and an almost still left. In the middle section he lifts the melody in stages, one small cell after another, up to a very high C, before a long descending scale played forte.
Everything depends on even sixteenths: the right hand runs at about five notes per second, peaking near seven. The falling scales need a thumb crossing prepared in advance; find where it lands and practise those spots on their own, slowly, with a loose wrist. In the climb through the middle, each group starts with a staccato eighth followed by two slurred sixteenths: keep that staccato clearly apart from the rest, or the rhythm blurs. The left hand, mostly chords in half and quarter notes, stays in the background. Keep it piano even when the right hand gets busy.
