Drawing on Thomas's popular opera Mignon, this fantasy captures the sentimental and brilliant aspects of the score. It exemplifies Ketterer's ability to condense complex orchestral colors into effective, idiomatic piano textures.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: a true singing tone, with the melody floating above the accompaniment; rubato that must breathe naturally without losing the pulse; and ornaments that need to sound effortless, not squeezed in.
Beyond that, expect sweeping arpeggio figures that must stay smooth across positions, and chord voicing — bringing out one note inside a handful of others.
Focus on balance within the left hand to ensure the lyrical bass lines do not overpower the delicate melodic ornamentation.
