These etudes by Ferenc Weisz are typical of late-Romantic pedagogical concert music intended for technical development. They focus on specific keyboard figurations presented with a display-oriented, bravura character.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: fast passage work that stays light and even at tempo; sweeping arpeggio figures that must stay smooth across positions; and fine finger independence within the hand.
The piece demands perfectly even, rapid finger work across shifting arpeggio patterns.
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.
Concert Study (Op.1 No.1) is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 7.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 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 Concert Study (Op.1 No.1) lasts about 3 minutes.
