This piece by Vetrov is a study in precision, utilizing driving sixteenth-note patterns. It is characterized by its strict rhythmic discipline and requirements for independent hand coordination.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: a left hand with real melodic or rhythmic responsibility of its own; continuous sixteenth-note figuration that must ripple, not chatter; and precise articulation — the difference between crisp and blurred is the piece.
The technical hurdle is achieving perfect synchronization between the hands in fast-moving passagework.
Comparable difficulty and character — good candidates for what to learn next.
A level or two down with the same spirit — ideal if this piece is still out of reach.
Where this piece's skills lead: slightly harder works making similar technical demands.
