Etude No. 6 Op. 25 in G-Sharp Minor composed by Frédéric Chopin is a technical study focusing on thirds, trilling them at a high speed. At one point, both hands play a chromatic-third scale. This etude is considered by some pianists as the most difficult of all the 24 etudes. – Valentina Lisitsa Wikipedia – Valentina Lisitsa Website
