G/F# Guitar Chord
G/F# is a G chord with F# as the bass note. F# is not a chord tone of G — it is a chromatic passing note in the bass that gives G/F# a distinct sound from a standard G voicing. The notes in context are F#, G, B, D. It is most naturally heard in the descending bass line G → G/F# → Em, where the bass walks down from G(43) through F#(42) to E(40) on the low E string. This three-chord motion is one of the most-played guitar progressions in rock, pop, and acoustic music.
Notes in the G/F# Chord
G/F# is a G chord with F# as the lowest sounding note. F# is not a chord tone of G — it is a chromatic passing note placed below the harmony. The notes in context are F#, G, B, D. Because F# sits outside the G chord structure, G/F# has a distinct colour from a standard G voicing and is most effective as a brief passing chord rather than a stable resting point.
What Does G/F# Mean?
In chord notation, a slash chord is written as Chord/Bass — the letter before the slash is the chord to play, and the letter after the slash is the specific note that should sound as the lowest pitch. For G/F#, this means: play G with F# in the bass.
Unlike a first or second inversion — where the bass note is always a chord tone — F# is not part of the G chord. This makes G/F# a chromatic slash chord rather than a standard inversion. F# acts as a passing note in the bass: a brief chromatic step that connects two harmonies more smoothly than a straight root-to-root jump would.
Guitarists use chromatic bass passing chords like G/F# to create stepwise bass movement in progressions where the natural root movement would otherwise produce a leap. The technique is borrowed from classical voice leading and is especially common in acoustic pop, folk, and singer-songwriter guitar.
Keys That Contain G/F#
G (the chord above the slash) is a diatonic chord in these keys. G/F# can be used in any context where G naturally appears:
Common Uses of G/F# in Progressions
G/F# is most often used as a passing chord rather than an opening or closing chord. It appears between root-position chords to create a stepwise bass line:

Frequently Asked Questions
What does G/F# mean?
G/F# is a slash chord — it means: play G with F# as the lowest note. Unlike a standard inversion, F# is not a chord tone of G. It is a chromatic passing note placed in the bass to create smooth stepwise movement between two chords.
Is G/F# the same as G?
No — G/F# and G do not contain the same notes. G uses its own chord tones only. G/F# adds F# as an extra bass note below the G harmony, giving it the notes: F#, G, B, D. This makes it a distinct voicing with a different colour.
How do you play G/F# on guitar?
Place your fingers according to the chord diagram above. The goal is to ensure F# sounds as the lowest note — on guitar this typically means playing F# on the lowest string used and muting any open strings below it. The "X" symbols in the diagram show which strings to mute.
What key is G/F# in?
G/F# most commonly appears in keys where G is diatonic: C Major, G Major, D Major. It functions as a chromatic passing chord between two adjacent harmonies rather than as a standalone chord with its own harmonic function within the key.
