The Note G

G as a musical pitch: its frequency, spellings, and the harmony built on top of it.

G is one of the most popular guitar keys — the open G chord rings with all six strings. G major's single sharp (F#) makes it accessible while still sounding full and resonant. Its reference octave pitch is 392 Hz (MIDI note 67). The major triad on G is G Major (G – B – D), and the minor triad is G Minor (G – Bb – D).
