Arthur Garnier's Op. 19 is a representative example of late-19th-century salon-style etudes. Its distinctiveness lies in its combination of bravura arpeggio figurations and melodic charm.
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; a true singing tone, with the melody floating above the accompaniment; and rubato that must breathe naturally without losing the pulse.
Balance the dynamic range to ensure the melody projects over the sweeping arpeggios.
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.
Etude N°1 (Op.19) 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.
