This is an alternate spelling of Aleksandrov's piece, reflecting the same sophisticated, modernist harmonic idiom. It is known for its melancholic mood and delicate contrapuntal sensitivity.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: chord voicing — bringing out one note inside a handful of others; several simultaneous layers, each needing its own dynamic level; and fine finger independence within the hand.
Beyond that, expect careful pedaling — clarity depends on the foot as much as the fingers.
Pay close attention to the pedaling to ensure the dissonant harmonies do not blur the melodic lines.
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.
