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.[1] Its relative minor is D-sharp minor (or enharmonically E-flat minor) and its parallel minor is F-sharp minor. Its direct enharmonic, G-flat major, contains six flats in its key signature.
The F-sharp major scale is:
Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The F-sharp harmonic major and melodic major scales are:
The scale degree chords of F-sharp major are:
F-sharp major is the key of the minuets in Haydn's "Farewell" Symphony and of the String Quartet No. 5 from his Op. 76, of Beethoven's Piano Sonata No. 24, Op. 78, Verdi's "Va, pensiero" from Nabucco, Mahler's unfinished Tenth Symphony, Korngold's Symphony Op. 40, and Scriabin's Fourth Piano Sonata. The key was the favorite tonality of Olivier Messiaen, who used it throughout his work to express his most exciting or transcendent moods, most notably in the Turangalîla-Symphonie and the piano cycle Vingt Regards sur l'enfant-Jésus.
Like G-flat major, F-sharp major is rarely used in orchestral music, other than in passing. It is more common in piano music. Some examples include a Nocturne and the Barcarolle by Chopin, the sonatas of Alexander Scriabin and several pieces from Grieg's Lyric Pieces. Shostakovich's String Quartet No. 14 is in this key.
Liszt was apparently fond of F-sharp major, having uplifting while meditative pieces like "Les jeux d'eaux à la villa d'este" from Années de Pèlerinage III, S.163 and "Bénediction de Dieu dans la Solitude" from the set Harmonies Poétiques et Religieuses S.173 in this key. The first polka in Smetana's "3 Polkas de Salon" is in F-sharp major, as is Polonaise No. 1 by Stanisław Moniuszko.
Despite the key rarely being used in orchestral music other than to modulate, it is not entirely uncommon in keyboard music. For orchestration of piano music, some theorists recommend transposing the music to F major or G major. If F-sharp major must be used, one should take care that B♭ wind instruments be notated in A-flat major, rather than G-sharp major (or E♮/B♮ instruments used instead, giving a transposed key of D major/G major).
In tuning systems where the number of notes per octave is not a multiple of 12, notes such as F♯ and G♭ are not enharmonically equivalent, nor are the corresponding key signatures. For example, the key of F-sharp major, with six sharps, is equivalent to G-flat major in 12-tone equal temperament, but in 19-tone equal temperament, it is equivalent to G-double-flat major instead, with 13 flats.
