A work by Claudio Espejo that emphasizes technical facility through extensive arpeggiated figures in the key of A-flat major. It is a stylistically standard Romantic etude requiring significant stamina.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: sweeping arpeggio figures that must stay smooth across positions; fast passage work that stays light and even at tempo; and chord voicing — bringing out one note inside a handful of others.
Focus on the coordination between both hands to ensure evenness in rapid passages.
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.
