FLAT (MUSIC)
(Redirected from Quarter flat)
In music, 'flat' means "lower in pitch." More specifically, in music notation, 'flat' means "lower in pitch by a semitone (half step)," and has an associated symbol (), which looks somewhat like a lowercase "b". The Unicode character '' (U+266D) can be used to display a flat sign.
Under twelve tone equal temperament, ''C flat'' for instance is the same as, or enharmonically equivalent to, ''B natural'', and ''G flat'' is the same as ''F sharp''. Note that in any other tuning system, such enharmonic equivalences in general do not exist.
'Double flats' also exist, which look like and lower a note by two semitones, or a whole step. Less often (in for instance microtonal music notation) one will encounter half, or three-quarter, or otherwise altered flats. The Unicode character '𝄫' (U+1D12B) represents the double flat sign.
The note ''A flat'' is shown in musical notation in Figure 1, together with ''A double flat''.
In tuning, flat can also mean "slightly lower in pitch". If two simultaneous notes are slightly out of tune, the lower-pitched one (assuming the higher one is properly pitched) is said to be flat with respect to the other.
