Piano Sonata no. 4 in F sharp major, op. 30

The Piano Sonata No. 4 in F♯ major, Op. 30, was written by Alexander Scriabin around 1903 and first published in 1904. It consists of two movements, Andante and Prestissimo volando, and is one of Scriabin's shortest piano sonatas; a typical performance takes about 8 minutes. The sonata is generally considered to be the beginning of Scriabin's middle period due to the newly mystical sonorities and tonal ambiguity of the first movement. It remains one of the most performed of Scriabin's sonatas.
