Exaerbio Op. 40 is a modern composition that contrasts stark, aggressive chords with lyrical interludes. Its harmonic structure pushes beyond traditional tonality.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: sharp dynamic and character contrasts held together in one arc; chord voicing — bringing out one note inside a handful of others; and careful pedaling — clarity depends on the foot as much as the fingers.
Beyond that, expect big chords that need weight without harshness.
Managing large, dissonant chords with a warm tone without creating harshness is key.
