This contemporary work explores rhythmic instability and modern digital-age textures through variation form. Its distinctive quality lies in the stark, mechanical approach to piano patterns.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: fast passage work that stays light and even at tempo; repeated-note passages that require controlled, springy fingerwork; and precise articulation — the difference between crisp and blurred is the piece.
Precision in rhythm and articulation of the rapid-fire note groups is the primary requirement.
