Joseph Ascher was a popular composer of salon virtuoso music in the mid-19th century. This piece is a characterful display work typical of the light bravura style of the era.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: sweeping arpeggio figures that must stay smooth across positions; fast passage work that stays light and even at tempo; and rubato that must breathe naturally without losing the pulse.
The piece requires nimble finger-agility for the rapid arpeggiated figures.
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.
Lesser-known works by the same hand, at a comparable level.
Dozia (Op.23) is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 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 Dozia (Op.23) lasts about 4 minutes.
