Ketterer was a prolific composer of salon fantasias who excelled at writing showy, idiomatic pieces for the concert hall. This work uses the heroic themes of Rossini's Guillaume Tell to create a dense, virtuosic piano texture.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: fast passage work that stays light and even at tempo; octave passages that demand a relaxed wrist to avoid tension; and sweeping arpeggio figures that must stay smooth across positions.
Beyond that, expect big chords that need weight without harshness.
At roughly 9 minutes, stamina and memory become part of the challenge — plan practice in sections.
Developing the endurance required for the lengthy stretches of rapid, brilliant figuration is the main pedagogical hurdle.
Comparable difficulty and character — good candidates for what to learn next.
A level or two down with the same spirit — ideal if this piece is still out of reach.
Where this piece's skills lead: slightly harder works making similar technical demands.
