F♯ major or F-sharp major is a major scale based on F♯, consisting of the pitches F♯, G♯, A♯, B, C♯, D♯, and E♯. Its key signature has six sharps.
Its relative minor is D♯ minor (or enharmonically E♭ minor). Its parallel minor is F♯ minor. Its enharmonic equivalent is G♭ major. In writing music for transposing instruments in B-flat or E-flat, it is preferable to use a G-flat rather than an F-sharp key signature.
F-sharp major is the key of the minuet in Joseph Haydn's "Farewell" Symphony, of Beethoven's Piano Sonata No. 24, 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, of Scriabin's Fourth Sonata. The key was the favorite tonality of Olivier Messiaen, who used it repeatedly throughout his work to express his most exciting or transcendent moods, most notably in the Turangalîla-Symphonie.
