F-sharp minor is a minor scale based on F♯, consisting of the pitches F♯, G♯, A, B, C♯, D, and E. Its key signature has three sharps. Its relative major is A major and its parallel major is F-sharp major (or enharmonically G-flat major).
The F-sharp natural minor scale is:
Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The F-sharp harmonic minor and melodic minor scales are:
Very few symphonies are written in this key, Haydn's Farewell Symphony being one famous example. George Frederick Bristow and Dora Pejačević also wrote symphonies in this key.
The few concerti written in this key are usually written for the composer himself to play, including Rachmaninoff's Piano Concerto No. 1, Scriabin's Piano Concerto, Wieniawski's Violin Concerto No. 1, Vieuxtemps's Violin Concerto No. 2, Bernhard Romberg's Cello Concerto Op. 30 and Koussevitzky's Double Bass Concerto.
In addition to the Farewell Symphony, Haydn's Piano Trio No. 40 (Hob. XV:26) and String Quartet Op. 50, No. 4 are in F-sharp minor.
More prominent piano pieces written in F-sharp minor include Schumann's Sonata No. 1 in F-sharp minor (1833-35), Chopin's Polonaise in F♯ minor, Scriabin's Third Sonata, and Ravel's Sonatine. The slow movement of Beethoven's Hammerklavier piano sonata is written in this key.
Handel set the sixth of his eight harpsichord suites of 1720 in F-sharp minor. Aside from a prelude and fugue from each of the two books of The Well-Tempered Clavier, Bach's only other work in F-sharp minor is the Toccata BWV 910. Mozart's only composition in this key is the second movement to his Piano Concerto No. 23 in A major. Wagner wrote a fantasy in F-sharp minor (WWV 22).
F-sharp minor is sometimes used as the parallel minor of G-flat major, for example in the ending of Alkan's op. 35 nro 10 in G-flat major. F-sharp minor is more practical to use with three sharps whis G-flat major's real parallel minor, G-flat minor, would have nine flats. (All seven flats and the first two flats double-flatted.)
