This improvisation focuses on the harmonic potential of perfect ninths as a structural building block. It is distinctive for its improvisational, stream-of-consciousness approach to contemporary keyboard harmony.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: careful pedaling — clarity depends on the foot as much as the fingers; rubato that must breathe naturally without losing the pulse; and a true singing tone, with the melody floating above the accompaniment.
Beyond that, expect chord voicing — bringing out one note inside a handful of others.
Mastering the control of resonance when dealing with large, open harmonic intervals is the main challenge.
