Alexander Scriabin's music has been described as mystical, lyrical, and idiosyncratic. He was known as the most innovative and controversial early modern Russian composer. His works were ignored for many years until recently and are now seen as "sincere expression(s) of genius."
The Two Etudes for Tuba or Bass Trombone and Piano from Op. 8 are early works of Scriabin, originally written for solo piano. They show lyricism, passion, moodiness, chromatic harmonies, and great expression. - the publisher
