Agnes Tschetschulin was a Finnish-born composer whose works remain relatively obscure in the standard piano repertoire. This piece utilizes characteristic syncopation and modal shifts associated with the 'Zingaresca' (Gypsy-style) dance.
The main difficulty lies in executing the rapid changes in rhythmic pulse and the dramatic dynamic shifts.
Comparable difficulty and character — good candidates for what to learn next.
Alla Zingaresca is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 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 Alla Zingaresca lasts about 3 minutes.
Alla Zingaresca is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
