If you want to play D7#5 on the ukulele, start with its notes: D, F#, A#, C. Its first ukulele voicing is a barre chord at fret 2: G string at fret 3 (middle finger); C string at fret 2 (index finger); E string at fret 2 (index finger); A string at fret 3 (ring finger). This is a 7th sharp 5th chord, and the sections below take you from the notes table to real fingerings, common mistakes and the musical contexts where D7#5 sounds right.
What notes are in the D7#5 chord?
The D7#5 chord is a 7th sharp 5th chord, and its notes are fixed: D, F#, A#, 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 D7#5 at a glance. On the ukulele, the barre chord voicing is the place to hear it in D7#5.
| Note | Interval |
|---|---|
| D | Root |
| F# | 3 |
| A# | #5 |
| 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 D7#5 are 3, #5, b7. Learn those intervals rather than memorising the shape alone, because the same interval pattern transposed to another root gives you the same quality of chord anywhere. On the ukulele, the notes appear in the order the fingering dictates, but the set of notes never changes.
D7#5 sounds sharp and colourful, a dominant chord that refuses to sound ordinary. That character comes straight from the intervals above, not from the instrument: the same notes on piano, guitar or ukulele carry the same colour, even though the voicing changes. On the ukulele, the barre chord of D7#5 puts those notes under your fingers in the order the fingering lists them.
Comparing D7#5 with its closest relatives helps to fix it in your ear. In short, 7#5 against dominant 7th: D7#5 raises the 5th to A# where the plain dominant 7th keeps the perfect 5th A. The raised 5th adds lift and tension at the same time. Hearing the comparison matters more than reading it: play D7#5, then play the chord it is compared with above, and let your ear find the note that changed. On the ukulele, the barre chord voicing is the place to hear it in D7#5.
How to play D7#5 on ukulele
On the ukulele, D7#5 has 3 voicings in the data below, and each one uses the same notes — D, F#, A#, C — in a different place on the neck. There are 3 voicings listed for D7#5 on the ukulele; learn the first, then add the others as you need them. 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 barre chord, D7#5 sits in around fret 1: G string at fret 3 (middle finger); C string at fret 2 (index finger); E string at fret 2 (index finger); A string at fret 3 (ring finger). It barres across strings 2 to 3 at fret 2 with the index finger. The barre is the hard part: the index finger must press every string from 2 to 3 evenly at fret 2, 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 D7#5 — D, F#, A#, C — sounds, with no buzz and no accidental open string.
The movable voicing is the voicing to learn if you want D7#5 in around fret 2: G string at fret 3 (middle finger); C string open; E string at fret 2 (index finger); A string at fret 5 (ring 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 D7#5 — D, F#, A#, C — sounds, with no buzz and no accidental open string.
Another way to play D7#5 is the movable voicing, in around fret 6: G string at fret 7 (middle finger); C string open; E string at fret 6 (index finger); A string at fret 9 (ring finger). The stretch is the challenge: the fretted notes span from fret 6 to fret 9, 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 D7#5 — D, F#, A#, C — sounds, with no buzz and no accidental open string.
Choosing between the voicings of D7#5 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 D7#5 up the neck to any key without changing the shape. When you change chords, pick the voicing of D7#5 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into D7#5 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the ukulele, the barre chord of D7#5 puts those notes under your fingers in the order the fingering lists them.
A short practice routine for D7#5 on the ukulele: 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.

Common mistakes
These are the mistakes that most often make D7#5 sound wrong on the ukulele, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Pressing too hard on the nylon strings. Ukulele strings need far less pressure than guitar strings, and pressing hard on D7#5 pulls the notes sharp and tires the hand. Use the lightest touch that gives a clean note, and keep your fingers close to the frets. On the ukulele, the barre chord voicing is the place to hear it in D7#5.
Playing a perfect 5th. If the 5th is A the chord is a plain dominant 7th. The sharpened 5th A# is the note that makes it altered. On the ukulele, start with the first voicing above and listen for the notes D, F#, A#, C in D7#5.
Confusing it with the augmented triad. The augmented triad has no 7th. D7#5 adds the flattened 7th C to the augmented triad — that 7th is essential. On the ukulele, the barre chord voicing is the place to hear it in D7#5.
Using it as a tonic. D7#5 is an altered dominant. It wants to resolve to the tonic a fourth above its root. On the ukulele, start with the first voicing above and listen for the notes D, F#, A#, C in D7#5.
Where D7#5 is used
D7#5 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 sharpened 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 D7#5 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the ukulele, the barre chord voicing is the place to hear it in D7#5.
Because D7#5 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 D7#5 in a progression in any key and hear how it connects to the chords around it. On the ukulele, start with the first voicing above and listen for the notes D, F#, A#, C in D7#5.
The same chord on other instruments is covered in D7#5 on guitar, D7#5 on piano, D7#5 on bass, and the scales that fit over it are the D major scale and the D minor pentatonic scale. Learning D7#5 on the ukulele and then checking it on another instrument is one of the best ways to fix the notes — D, F#, A#, C — in your memory, because the notes stay the same while everything else changes.
Practising D7#5
A short worked example makes D7#5 concrete. Play the four-chord progression G – D – Em – C in G major, the key D7#5 most often resolves toward: G – D – Em – C. Play each chord for one bar at a slow tempo, and listen to how D7#5 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 D7#5 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the ukulele, the barre chord of D7#5 puts those notes under your fingers in the order the fingering lists them.
For a second exercise, play D7#5 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 D7#5 is built for when it acts as a dominant. Finish by playing D7#5 on its own, slowly, and naming each note out loud as you play it: D, F#, A#, 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 ukulele, the barre chord voicing is the place to hear it in D7#5.
Frequently asked questions
Is D7#5 hard to play on the ukulele?
