A G major etude by Colin Peter Snuggs, focusing on velocity and the fluidity of scales. It utilizes standard keyboard patterns adapted for a contemporary pedagogical approach.
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; fine finger independence within the hand; and precise articulation — the difference between crisp and blurred is the piece.
Development of finger speed and evenness throughout the rapid scale passages is required.
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.
Etude No. 13 G major 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.
