F♯ (F-sharp; also known as fa dièse or fi) is the seventh semitone of the solfège. It lies a chromatic semitone above F and a diatonic semitone below G, thus being enharmonic to sol bémol or G♭ (G-flat). However, in some temperaments, it is not the same as G♭. G♭ is a major third below B♭, whereas F♯ is a major third above D (a minor third below A). Another enharmonic note is E (E-double sharp).
