F is a musical note, the fourth above C or fifth below C. It is the fourth note and the sixth semitone of the solfège. It is also known as fa in fixed-do solfège.[1] It has enharmonic equivalents of E (E-sharp)[2] and Gdouble flat (G-double flat),[3] amongst others.

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of Middle F (F4) is approximately 349.228 Hz.[4] See pitch (music) for a discussion of historical variations in frequency.

E (German: Eis)[5] is a common enharmonic equivalent of F, but is not regarded as the same note. E is commonly found before F in the same measure in pieces where F is in the key signature, in order to represent a diatonic, rather than a chromatic semitone; writing an F with a following F is regarded as a chromatic alteration of one scale degree. Though E and F sound the same in any 12-tone temperament, other tunings may define them as distinct pitches.
