Décalages is a contemporary work exploring complex rhythmic shifts and abrupt textural changes. Its distinctiveness lies in its experimental use of asymmetrical accents and dissonant tonal clusters.
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; sharp dynamic and character contrasts held together in one arc; and polyrhythms that have to lock together without sounding mechanical.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece, and fine finger independence within the hand.
The main difficulty lies in mastering the irregular rhythmic groupings and maintaining clarity at high speeds.
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.
Décalages is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above.
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 Décalages lasts about 5 minutes.
