Etude Op. 10, No.1 in C major, composed by Fryderyk (Frederic) Chopin, is a technical study in reach and arpeggios for the piano.
The work is executed at an Allegro tempo. The time-signature Common time is according to the first French, English, and German editions. Chopin's own manuscript reads Cut time.
The right hand gauntlet consists entirely of broad arpeggios in semiquavers on modulating scales. The left hand plays the deep melody in slow, droning octaves. The Piece requires a high level of technical skill to perform accurately.
