ÃÂtude in D-sharp minor, Op. 8, No. 12, is an étude for piano composed by Alexander Scriabin in 1894. Its technical challenges include numerous jumps in the left hand, repetitive chord strikes, and abundant octaves. It was a favorite encore of Vladimir Horowitz.
The tempo marking for the piece is around 100-112 beats per minute. The right hand is always playing octaves except for the piece's ending.
