Musical note indicated by placing the symbols in the key signature, which then apply implicitly to all occurrences of corresponding notes. Explicitly noted accidentals can be used to override this effect for the remainder of a bar. A special accidental, the natural symbol , is used to indicate an unmodified pitch. Effects of key signature and local accidentals do not accumulate. If the key signature indicates G, a local flat before a G makes it G (not G), though often this type of rare accidental is expressed as a natural, followed by a flat () to make this clear. Likewise (and more
F (musical note) 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 (E and F do not sound the same, except in some tunings that define the notes in that way). F (musical note) F is a musical note, the fourth above C. It is also known as fa in fixed-do solfège. It has enharmonic equivalents of E and G, amongst others. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of
