G{{music|flat}} (G-flat) or sol bémol is the seventh semitone of the solfège.

It lies a diatonic semitone above F and a chromatic semitone below G, thus being enharmonic to F{{music|sharp}} (F-sharp) or fa dièse. However, in some temperaments, it is not the same as F{{music|sharp}}. G{{music|flat}} is a major third below B{{music|flat}}, whereas F{{music|sharp}} is a major third above D (a minor third below A).

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the G{{music|b}} semitone is approximately 369.994 Hz. See pitch (music) for a discussion of historical variations in frequency.
