This is the same composition as the Liadov entry, listed under the alternative spelling of the composer's name. It remains a brilliant exercise in light, rapid finger work.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: fast passage work that stays light and even at tempo; precise articulation — the difference between crisp and blurred is the piece; and fine finger independence within the hand.
Ensure the 'buzzing' effects remain light and do not require heavy weight into the keys.
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.
Dance of the Mosquito 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.
