Chopin - Etude Op. 25 No. 1 in A-flat Major

Étude Op. 25, No. 1 in A-flat major is a solo piano work composed by Frédéric Chopin in 1836, and published in 1837. The work consists entirely of rapid arpeggios and harmonic modulations based on A-flat major. Robert Schumann praised this work in a dissertation on the Études; calling it “a poem rather than a study“, he coined for it the alternate name “Aeolian Harp”
