G♭ (musical note)
G♭ (G-flat) (Ges 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♯ (F-sharp) or fa dièse. However, in some temperaments, it is not the same as F♯. G♭ is a major third below B♭, whereas F♯ 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♭ semitone is approximately 369.994 Hz. See pitch (music) for a discussion of historical variations in frequency.

gollark: I would suspect it being a distro thing, but I have multiMC installed from the AUR and recompiling it didn't help.

gollark: I checked, I have more but they all break.
gollark: I only have something like three installed as far as I know, and they're all broken.
gollark: I'd kind of expect other people to have noticed and reported this if it is actually a general problem with these versions, since I'm using calibre and qt from the repos.
