D7b5 is a 7th flat 5th chord, and on the guitar it is played from the notes D, F#, G#, C. Its first guitar voicing is the open position: low E string at fret 2 (middle finger); A string at fret 3 (little finger); D string open; G string at fret 1 (index finger); B string at fret 3 (little finger); high e string at fret 2 (ring finger). This page is a complete reference for it: notes and intervals, fingerings, mistakes to avoid, the keys it belongs to and a short practice routine.
What notes are in the D7b5 chord?
The D7b5 chord is a 7th flat 5th chord, and its notes are fixed: D, F#, G#, C. Every voicing on every instrument uses these same notes, in some order and in some octave — change one of them and you are playing a different chord. The table below lists each note with its interval from the root D, so you can see the structure of D7b5 at a glance. On the guitar, start with the first voicing above and listen for the notes D, F#, G#, C in D7b5.
| Note | Interval |
|---|---|
| D | Root |
| F# | 3 |
| G# | b5 |
| C | b7 |
The root is D, the note the chord is named after and the note your ear hears as home. Above it, the intervals in D7b5 are 3, b5, b7. Once you know the intervals, you can build D7b5 from any root by counting the same semitone steps, which is how the chord works in every key. On the guitar, the notes appear in the order the fingering dictates, but the set of notes never changes.
D7b5 sounds tense, dark and jazzy — the flattened 5th ({flat5}) gives the dominant chord a chromatic edge. The colour is strongest when all the notes ring clearly. A muted chord tone, especially the 3rd or the 7th where the chord has one, flattens the character of D7b5 noticeably. On the guitar, the open position voicing is the place to hear it in D7b5.
Comparing D7b5 with its closest relatives helps to fix it in your ear. In short, 7b5 against dominant 7th: D7b5 flattens the 5th to G# where the plain dominant 7th keeps the perfect 5th A. That one change adds a whole new layer of tension. Play both chords slowly, one after the other, and notice which note moves. Naming that note out loud while you play is the fastest way to learn the difference. On the guitar, the open position of D7b5 puts those notes under your fingers in the order the fingering lists them.
How to play D7b5 on guitar
On the guitar, D7b5 has 3 voicings in the data below, and each one uses the same notes — D, F#, G#, C — in a different place on the neck. The first voicing below is the one to learn first, and the alternatives cover the rest of the neck. Finger numbers below use 1 for the index finger, 2 for the middle finger, 3 for the ring finger and 4 for the little finger, and x means the string is not played.
For the open position, D7b5 sits in open position: low E string at fret 2 (middle finger); A string at fret 3 (little finger); D string open; G string at fret 1 (index finger); B string at fret 3 (little finger); high e string at fret 2 (ring finger). This voicing is comfortable because the fretted notes sit close together, from fret 1 to fret 3, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in D7b5 — D, F#, G#, C — sounds, with no buzz and no accidental open string.
Another way to play D7b5 is the barre chord, in open position: low E string at fret 2 (middle finger); A string at fret 3 (little finger); D string open; G string at fret 1 (index finger); B string at fret 1 (index finger); high e string at fret 2 (ring finger). It barres across strings 4 to 5 at fret 1 with the index finger. The barre is the hard part: the index finger must press every string from 4 to 5 evenly at fret 1, so roll it slightly onto its bony side and keep it close to the fret wire. If the barre buzzes, move it a fraction closer to the fret and press from the arm, not the thumb alone. Strum or pluck it slowly first and check that every note in D7b5 — D, F#, G#, C — sounds, with no buzz and no accidental open string.
For the movable voicing, D7b5 sits in around fret 2: low E string at fret 2 (index finger); A string at fret 3 (middle finger); D string open; G string at fret 5 (little finger); B string at fret 3 (ring finger); high e string at fret 4 (little finger). The stretch is the challenge: the fretted notes span from fret 2 to fret 5, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in D7b5 — D, F#, G#, C — sounds, with no buzz and no accidental open string.
Choosing between the voicings of D7b5 is a musical decision, not a right-or-wrong one. The open or low-position voicing rings the most and suits strumming, while a barre or movable voicing lets you slide D7b5 up the neck to any key without changing the shape. When you change chords, pick the voicing of D7b5 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into D7b5 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the guitar, start with the first voicing above and listen for the notes D, F#, G#, C in D7b5.
A short practice routine for D7b5 on the guitar: play the first voicing four times slowly, checking each note, then change to it from the chord a fourth above D and back, four times, at a slow tempo. Then play the second voicing the same way. If a note buzzes, stop and fix the finger placement rather than playing through the buzz — clean notes at a slow tempo become clean notes at full tempo, while buzzes practised fast become habits. Use the Guitar Chord Finder to see the diagram for D7b5 while you practise, and the Chord Finder to compare it with the same chord on other instruments.
Common mistakes
These are the mistakes that most often make D7b5 sound wrong on the guitar, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Voicing it too low. The flattened 5th low down can sound muddy against the root. Keep G# in a higher octave. On the guitar, start with the first voicing above and listen for the notes D, F#, G#, C in D7b5.
Overusing altered dominants. A run of altered chords loses its effect. Use D7b5 where the tension earns its place — before a resolution. On the guitar, the open position of D7b5 puts those notes under your fingers in the order the fingering lists them.
Barre collapsing on the high strings. In a barre voicing of D7b5, the high strings are the ones that buzz first, because the index finger presses hardest near the thumb. If the top notes of D7b5 sound dead, roll the barring finger slightly toward the fret and press from the arm, not from squeezing the neck. On the guitar, start with the first voicing above and listen for the notes D, F#, G#, C in D7b5.
Playing a perfect 5th. If the 5th is A the chord is a plain dominant 7th. The flattened 5th G# is the note that makes it altered. On the guitar, start with the first voicing above and listen for the notes D, F#, G#, C in D7b5.
Where D7b5 is used
D7b5 is not a diatonic triad in any major or minor key, because it is an extended or altered chord, but its base triad belongs to the key of D major, the key of G major, the key of A major. an altered dominant in jazz, where the flattened 5th adds tension before a resolution. As a dominant-type chord it also points toward G major, the key a perfect fourth above D, which is the tonic it most often resolves to. That is where D7b5 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the guitar, the open position voicing is the place to hear it in D7b5.
Because D7b5 is an extended or altered chord, it appears in progressions as a colour or a dominant rather than as a diatonic staple. Try it in place of the plain D triad in a progression you already know, and listen to how the extra notes change the feel — that substitution is the usual way extended chords enter real music. The Chord Progression Builder lets you try D7b5 in a progression in any key and hear how it connects to the chords around it. On the guitar, the open position voicing is the place to hear it in D7b5.
The same chord on other instruments is covered in D7b5 on piano, D7b5 on ukulele, D7b5 on bass, and the scales that fit over it are the D major scale and the D minor pentatonic scale. Learning D7b5 on the guitar and then checking it on another instrument is one of the best ways to fix the notes — D, F#, G#, C — in your memory, because the notes stay the same while everything else changes.
Practising D7b5
A short worked example makes D7b5 concrete. Play the four-chord progression G – D – Em – C in G major, the key D7b5 most often resolves toward: G – D – Em – C. Play each chord for one bar at a slow tempo, and listen to how D7b5 sounds in that sequence — whether it feels like home, like a lift, or like a chord on its way somewhere else. Then play the same four chords in a different order, starting on D7b5 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the guitar, the open position of D7b5 puts those notes under your fingers in the order the fingering lists them.
For a second exercise, play D7b5 and then the chord a fourth above D, back and forth, four times each. That move — a chord and the chord a fourth above it — is the most common resolution in Western music, and it is the move D7b5 is built for when it acts as a dominant. Finish by playing D7b5 on its own, slowly, and naming each note out loud as you play it: D, F#, G#, C. Naming the notes while you play them is what turns a shape into knowledge you can use in any key. Test yourself with the Practice Chord Quiz and keep time with the Metronome as the tempo rises. On the guitar, the open position of D7b5 puts those notes under your fingers in the order the fingering lists them.
Frequently asked questions
Where is D7b5 used?
D7b5 is an altered V chord in jazz, used before a resolution to the tonic, and as a tritone substitute for the dominant a tritone away. On the guitar, check the first voicing above for that note.
How do you play D7b5 on the guitar?
The first voicing is the open position: frets 2–3–0–1–3–2, fingers 2–4–0–1–4–3, on the guitar. That voicing uses the notes D, F#, G#, C, and it is the one to learn first. The page above lists more voicings for D7b5, so you can choose the shape nearest the chords around it.
Is D7b5 hard to play on the guitar?
It depends on the voicing. The first voicing of D7b5 on the guitar is the easiest starting point, and the movable voicings further up the neck are harder because they need a barre or a wider stretch. Practise the first voicing cleanly at a slow tempo before you try the others, and the harder shapes will come more easily.
What is the easiest voicing of D7b5 on the guitar?
The open position is the easiest voicing listed for D7b5 on the guitar: frets 2–3–0–1–3–2, fingers 2–4–0–1–4–3. Learn that shape first, get every note ringing cleanly, and only then move on to the alternative voicings further up the neck.
What notes are in D7b5?
D7b5 contains D, F#, G#, C: root D, major 3rd F#, flattened 5th G# and flattened 7th C. The flattened 5th is the note that makes it an altered dominant. On the guitar, check the first voicing above for that note.
