'''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".Schumann quoted by Kullak, quoted by James Huneker in ''[http://www.gutenberg.org/catalog/world/readfile?pageno=61&fk_files=9283 Chopin: the Man and His Music]'' (1900). It is also sometimes known as "The Shepherd Boy," following an unsupported tale by Kleczy\u0144ski that Chopin advised a pupil to picture a shepherd boy taking refuge in a grotto to avoid a storm playing the melody on his flute.Johnson, p. 80
