Wolff’s fantasia on Halévy's 'Les martyrs' is a typical example of the 19th-century operatic fantasy. It weaves themes from the stage into a highly emotional and technically demanding piano structure.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: a true singing tone, with the melody floating above the accompaniment; sweeping arpeggio figures that must stay smooth across positions; and ornaments that need to sound effortless, not squeezed in.
Beyond that, expect chord voicing — bringing out one note inside a handful of others, and rubato that must breathe naturally without losing the pulse.
At roughly 9 minutes, stamina and memory become part of the challenge — plan practice in sections.
The piece demands significant expressive control, requiring the player to balance operatic cantabile playing with complex, fast-moving ornamental accompaniment.
