What is g flat?

G flat is a musical term used to describe a note that is one half step lower than G natural. In terms of pitch, G flat is the same as F sharp. It is denoted by the symbol "Gb" in written music notation.

In the context of a piano or keyboard, G flat is represented by the black key to the left of G natural. It is also the enharmonic equivalent of F sharp, meaning that it is the same note with a different name.

G flat is commonly used in music theory and composition, particularly in keys and scales that contain flats. It can also be found in various chords, such as Gb major and Gb minor.
