F-sharp major is a major scale based on F-sharp, consisting of the pitches F♯, G♯, A♯, B, C♯, D♯, and E♯. Its key signature has six sharps.
Its relative minor is D♯ minor, and its parallel minor is F♯ minor. Its enharmonic equivalent is G♭ major.
F-sharp major is the key of Beethoven's Piano Sonata, Op. 78, of Chopin's Barcarolle, of Liszt's Hungarian Rhapsody no. 2, of Mahler's unfinished Tenth Symphony, Erich Korngold's Symphony Op. 40, and Scriabin's Fourth Sonata.
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.
Despite the key rarely being used in orchestral music other than to modulate, it is not entirely uncommon in keyboard music, as in the sonatas of Scriabin. For orchestration of piano music, some theorists recommend transposing the music to F major or G major. If F-sharp major must absolutely be used, one should take care that B-flat wind instruments be notated in A-flat major, rather than G-sharp major.
The Presentation of the Rose scene in Act Two of Richard Strauss's opera Der Rosenkavalier is written in F-sharp major.
