This early Mendelssohn work is a driving, moto-perpetuo style étude that demonstrates his youthful mastery of keyboard textures. It is characterized by its restless motion and crisp, clean articulation throughout.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: fast passage work that stays light and even at tempo; continuous sixteenth-note figuration that must ripple, not chatter; and precise articulation — the difference between crisp and blurred is the piece.
Beyond that, expect a left hand with real melodic or rhythmic responsibility of its own.
The main challenge is maintaining a consistent pulse and clarity in the rapid, continuous sixteenth-note lines.
