This work is synonymous with the Leybach Op. 27 piece listed earlier, focusing on 'La Sonnambula'. It serves as a standard example of mid-Romantic salon fantasias based on popular operatic melodies.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. 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 a left hand with real melodic or rhythmic responsibility of its own.
The main challenge is balancing the lyrical operatic melody against the lighter, broken-chord accompanimental figures.
