F is a musical note, the fourth above C. It is also known as fa in fixed-do solfège.

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. See pitch (music) for a discussion of historical variations in frequency.

Common scales beginning on F[edit]

  • F Major: F G A B C D E F
  • F Natural Minor: F G A B C D E F
  • F Harmonic Minor: F G A B C D E F

E sharp[edit]

E 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.
