This piece uses strong harmonic dissonance to mirror its title, reflecting a modern approach to the musical expression of disappointment. The writing features complex layers of thematic development over a static bass.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: a true singing tone, with the melody floating above the accompaniment; sharp dynamic and character contrasts held together in one arc; and several simultaneous layers, each needing its own dynamic level.
The student must balance the layered textures to ensure the dramatic high-points are clearly articulated.
