A moderately technical fantasy based on Ambroise Thomas's popular opera. It utilizes common Romantic keyboard figurations to evoke the dramatic flair of the original stage work.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: a true singing tone, with the melody floating above the accompaniment; ornaments that need to sound effortless, not squeezed in; and sweeping arpeggio figures that must stay smooth across positions.
Beyond that, expect continuous sixteenth-note figuration that must ripple, not chatter, and rubato that must breathe naturally without losing the pulse.
The student must manage the expressive rubato required for the operatic vocal lines.
