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".[1] It is also sometimes known as "The Shepherd Boy," following an unsupported tale by Kleczyński 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.[2]
Structure
First measures of Chopin's Étude Op. 25, No. 1. (Urtext edition).
This étude comprises a right-hand melody and supportive bass line, the accompaniment consisting of broken chords, provided by the inner voices of both hands, usually in semiquaver-tuplets. The left hand introduces polyrhythms from time to time. The principal melody is presented by the right hand on the first note of each group of sextuplets, with occasional counter-melodies provided by the inner voices.
The distinctive theme is presented in A-flat major. Through metamorphic modulations to closely related keys, it eventually arrives at a brief episode in the remote key of A major, but culminates with an intense climax in the home key, and a momentary reference to the original thematic material, which flows easily into the coda.
Technically, the piece requires dexterity to play the six-tuples fast enough, and to be able to move the hand across intervals as large as a 13th in the middle. The inner voice figures consist of repeated figures of arpeggiated chords. Schumann commented on Chopin's subtle emphasis on certain melodies throughout this piece.[3] One difficulty the étude presents is the voicing of the inner counter-melodies. The three annotated studies by Leopold Godowsky on this etude exploit this aspect of this piece and also introduce the student to further possibilities in the Chopin original.[citation needed]
