This is a virtuosic parlor fantasy based on themes from the opera Ruy Blas. It features elaborate pianistic figurations typical of the mid-19th-century operatic transcription tradition.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: ornaments that need to sound effortless, not squeezed in; fast passage work that stays light and even at tempo; and sweeping arpeggio figures that must stay smooth across positions.
Beyond that, expect a true singing tone, with the melody floating above the accompaniment, and continuous sixteenth-note figuration that must ripple, not chatter.
Mastering the rapid, ornate passage work while maintaining a clear operatic melody in the right hand is the primary hurdle.
