What is "g minor"

n. 1 (context music English) a minor key with the notes G, A, B♭, C, D, E♭, F 2 (context music English) the minor chord with a root of G

G minor is a minor scale based on G, consisting of the pitches G, A, B, C, D, E, and F. For the harmonic minor scale, the F is raised to F. Its relative major is B-flat major, and its parallel major is G major.

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. G minor is one of two flat key signatures that require a sharp for the leading-tone (the other is D minor).
