This contemporary work focuses on melodic interaction between the registers. Its distinctiveness lies in its minimalist approach to harmonic progression.
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; chord voicing — bringing out one note inside a handful of others; and precise articulation — the difference between crisp and blurred is the piece.
Focus on maintaining a clear, singing tone in the melodic lines against softer accompanying voices.
