F-sharp major is the key of the minuet in Joseph Haydn's "Farewell" Symphony, of Beethoven's Piano Sonata, Op. 78, of Chopin's Barcarolle, of Liszt's Hungarian Rhapsody No. 2, of Mahler's unfinished Tenth Symphony, of Erich Korngold's Symphony Op. 40, and of Scriabin's Fourth Sonata. The key was the favourite tonality of Olivier Messiaen, who used it repeatedly throughout his work to express his most exciting or transcendent moods, most notably in the Turangalîla Symphony.
In a few scores, the F-sharp major key signature in the bass clef is written with the sharp for the A on the top line.
