Known as the "Sunshine" Etude.

Étude Op. 10, No. 8 in F major is a technical study composed by Frédéric Chopin. This work follows on from No. 7 as being primarily another work concerned with counterpoint. In this case, however, the principal melody is in the left hand, the secondary being embedded in the arpeggios of the right hand. As with many of the études, the work is divided into three sections – bars 1–28, 29–60 and 61–95.
