Vilbac was a prolific arranger whose piano fantasies served to popularize grand opera in the 19th-century salon. This piece strings together the hit melodies of La Sonnambula with idiomatic keyboard passage-work.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: fast passage work that stays light and even at tempo; precise articulation — the difference between crisp and blurred is the piece; and sweeping arpeggio figures that must stay smooth across positions.
Beyond that, expect careful pedaling — clarity depends on the foot as much as the fingers.
Ensure that the rapid passage-work does not sacrifice the rhythmic stability of the underlying waltz-like themes.
