Artur Schnabel's Diabolique is a challenging exercise in harmonic tension. It is distinct for its angular melodic lines that defy traditional tonal centers.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: sharp dynamic and character contrasts held together in one arc; chord voicing — bringing out one note inside a handful of others; and precise articulation — the difference between crisp and blurred is the piece.
Students must navigate the irregular voicing patterns while maintaining strict rhythmic integrity.
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.
Diabolique is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 9.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Diabolique lasts about 3 minutes.
