Vasilenko’s 'Au soleil' is a bright, optimistic work that contrasts with the heavier repertoire of his contemporaries. It features light, shimmering arpeggios that mimic the warmth of the sun.
The piece requires a light, transparent touch in the right-hand figures to maintain the 'sunny' character throughout.
Comparable difficulty and character — good candidates for what to learn next.
