Silvestre Revueltas's 'El afilador' is a vivid musical depiction of the itinerant knife sharpener, a staple figure of Mexican street life. It utilizes sharp, percussive articulation and rhythmic drive to mimic the repetitive mechanical sounds of the trade.
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; precise articulation — the difference between crisp and blurred is the piece; and a left hand with real melodic or rhythmic responsibility of its own.
Beyond that, expect sharp dynamic and character contrasts held together in one arc.
Focus on crisp, non-legato articulation and maintaining a steady mechanical pulse throughout the piece.
