D/F# Guitar Chord
D/F# is the first inversion of D, built from F#, A, D with F# as the lowest sounding note. It contains the same pitches as D. The slash notation specifies that F# sounds in the bass instead of the root. It most commonly appears in the key of G as part of a stepwise descending bass line: G then D/F# then Em, with the bass walking down from G to F# to E on the low E string. This three-chord motion is one of the most-played progressions in acoustic guitar and worship music.
Notes in the D/F# Chord
D/F# is the first inversion of D. It contains 3 notes: F#, A, D. These are the same pitches as D, but with F# as the lowest sounding note. Because the notes are identical to D, D/F# carries the same harmonic colour. The distinction lies in the bass: changing which note sits lowest reshapes the voicing and enables smoother bass-line movement between chords.
What Does D/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 D/F#, this means: play D with F# in the bass.
Because F# is the third of D, D/F# is specifically called the first inversion of D. An inversion does not change the notes in the chord. It only changes which note sits at the bottom, which affects how the chord sounds in context and how smoothly it connects to the chords around it.
Guitarists use slash chords primarily for smooth bass-line movement. Instead of the bass jumping from root to root between chords, a well-placed slash chord creates a stepwise (scale-like) bass line that makes a progression feel connected and natural. This technique is borrowed from classical voice leading and is used across every genre of modern music.
Keys That Contain D/F#
D (the chord above the slash) is a diatonic chord in these keys. D/F# can be used in any context where D naturally appears:
Common Uses of D/F# in Progressions
D/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 D/F# mean?
D/F# is a slash chord — it means: play D with F# as the lowest note. The letter before the slash (D) is the chord quality, and the letter after the slash (F#) is the bass note. D/F# is the first inversion of D.
Is D/F# the same as D?
D/F# and D contain exactly the same notes: F#, A, D. The difference is which note sounds lowest. In D, the root (D) is in the bass. In D/F#, F# is in the bass instead. This creates a different voicing and a smoother bass line in progressions.
How do you play D/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 either playing F# on the lowest string used, or muting any lower strings that don't contribute to the voicing. The "X" symbols in the diagram show which strings to mute.
What key is D/F# in?
D/F# appears in the same keys as D: G Major, D Major, A Major. It functions as an inversion of D within those keys rather than as a separate chord — it shares the same harmonic function, just with a different bass note.
