The B7 chord on a baritone ukulele is a dominant seventh built from the notes B–D#–F#–A; it gives strong tension that wants to resolve, commonly to E. You can play a full, clear B7 in one quick shape and several compact alternatives that fit strumming, fingerstyle, or quick changes.
Play B7 right now on your baritone ukulele (fast chord shapes and fingering)
Beginner-friendly B7 (open): D–G–B–E strings frets 1–2–0–2 (index 1 on D1, middle 2 on G2, B open, ring 3 on E2). That yields the notes B (B string open), D# (D1), F# (E2), and A (G2) — the complete dominant seventh sound.
Compact higher inversion (use when you want a tighter, higher sound): D–G–B–E at 9–8–7–5. Fingering example: index on E5 (A), middle on G8 (D#), ring on B7 (F#), pinky on D9 (B). Same chord tones, different texture and less low end.
Partial 3‑note voicing for an easy or mellow B7: mute the low D string and play x–2–0–2 (G2, B0, E2). That gives A–B–F#, which reads as a B7 color without the D#; useful for singing or quick rhythm parts.
Quick tips for clean sound: place fingertips just behind the fret for a crisp note; angle fingers so they press only their target strings and avoid flattening across neighbors; keep movement small — lift fingers vertically rather than sweeping the hand when shifting chords.
Common open B7 variations and when to use them
Full voicing (1–2–0–2) delivers a balanced chord with bass presence and clear third; use it for rhythm parts and full-sounding comping.
Three-note shapes (x–2–0–2 or x–2–0–0) trade low bass for clarity and ease. Use them for fingerstyle, vocal accompaniment, or when the bass is covered by another instrument.
Higher inversions (9–8–7–5) sit well for single-note runs, solo comping, or when you want the chord to cut through a mix. They sound thinner but brighter.
Which voicing fits a genre: use fuller shapes for folk and pop; partial, sparser shapes for singer-songwriter settings; higher, tightly voiced positions for blues or rock leads where the chord must not clash with solos.
Why B7 feels different on a baritone (D–G–B–E tuning and theory behind the sound)
Baritone tuning D–G–B–E matches the top four strings of a guitar, so many guitar B7 fingerings transfer directly. That makes moving shapes and inversions intuitive if you know guitar voicings.
Interval breakdown: root = B, major third = D#, perfect fifth = F#, flat seventh = A. The flat‑7 (A) adds pull; that pull is what defines the dominant function and makes B7 want to resolve to E.
Harmonic role: B7 commonly functions as the V7 in E major or E minor modal moves. Use it as a primary tension chord before landing on E (I) or to spice a secondary dominant chain like V/V into A or ii–V in modal contexts.
The “b7” interval (flat seventh) on baritone uke and scale context
Find the flat‑7 (A relative to a B root) across the fretboard: D string fret 7 = A, G string fret 2 = A, B string fret 10 = A, E string fret 5 = A. Memorize those spots and you can drop the b7 into voicings anywhere.
Mixolydian context: B Mixolydian (B C# D# E F# G# A) keeps the major third and adds the flat‑7; it works well for major‑key solos over B7. Blues context: the b7 shows up in riffs and turnarounds; combine the b7 (A) with the minor‑third or blues notes for grit.
Simple run to highlight the b7: play B (B string 0) → A (G string 2) → F# (E string 2) → D# (D string 1). Short, memorable, and it frames the dominant tension in a single line you can loop.
Movable shapes, barre options and voicing strategies for B7
Moveable approach: use the three‑note shape on G–B–E (x–n–n–n) as a movable texture. Keep the same fretting pattern and slide along the neck to create V7 chords on other roots.
Partial‑barre trick: place your index as a mini‑barre across G–B–E at a given fret and add one or two fingers to form fuller dominant shapes. That preserves voicing while reducing finger travel.
Voice‑leading tip: when shifting between chords, keep either the flat‑7 (A) or the major third (D#) as a common tone when possible. Minimal movement creates smoother progressions and clearer bass lines.
Inversions and triad-based B7 voicings
First inversion (D# in the bass) brightens the chord and removes the low root: try D–G–B–E frets 1–0–2–2 (D# as lowest note if arranged on the neck). Second inversion (F# in the bass) emphasizes stability and sits well under vocal parts.
Triad voicings: play the B triad shapes across three strings and add the flat‑7 as a passing tone for color. For example, play a B triad on G–B–E and sneak the A on the next beat to imply B7 without full fingering complexity.
Doubling open strings: keep open B or high E where usable to enrich texture. A single open string doubled with a fretted tone often gives a fuller sound without extra fingers.
Using B7 in progressions and real songs on baritone ukulele
Classic progressions: V7 → I (B7 → E), secondary dominants (use B7 as V/V to lead into A), 12‑bar blues in E often uses B7 as the IV or quick dominant depending on arrangement.
Arrangement tips: place B7 right before your resolution to E for strong release. Use partial voicings during verses so vocals sit in front; switch to fuller B7 voicings for choruses or turnaround sections.
Three quick play‑along examples: 1) Simple blues in E: | E | E | B7 | B7 | A | E | B7 | E | — strum steady 8ths, emphasize beats 2 and 4. 2) Folk walkdown: | E | B7 | C#m | A | — use B7 on beats 3–4 as a passing dominant. 3) II–V feel: | F#m7 | B7 | Emaj7 | — play B7 with a short arpeggio pattern before resolving.
Capo and transposition tricks for easier B7 use
Capo trick: put a capo at fret 2 and play an A7 open shape — the instrument sounds as B7 but uses simpler fingering. This keeps vocal range stable while making chord shapes friendlier.
Transpose cheat‑sheet: if B7 feels hard, move the song down a whole step to A7 for simpler left‑hand shapes, or use capo up 2 and play open A shapes to keep the original pitch. Decide whether you need the baritone’s low B bass; if so, avoid capoing that changes low-end character.
When to keep low voicing: use the low root B for depth in ballads or steady rhythm. Move up the neck when you want articulation, separation from other instruments, or tighter voicings for ensemble playing.
Embellishments, extensions and common B7 alterations on baritone uke
B7sus4 (adds E instead of D#): D–G–B–E at 2–2–0–2 produces B–E–F#–A — use it to delay resolution without removing the dominant color.
B7b5 (lowers the fifth): try D–G–B–E at 1–2–0–1 for B–D#–B–F — that altered fifth gives a tense, jazzy edge useful before chromatic moves.
Simple passing chords: slide the B7 shape up a fret for a chromatic approach or momentarily play B7sus4 before resolving to B7 to smooth voice leading between chords.
Technique hacks and practice exercises for clean, musical B7s
Fast change drill: set a metronome at 60 bpm and practice alternating B7 → E at quarter‑note changes for 2 minutes; increase tempo in 5 bpm increments while keeping every note clear.
Economy fingering pattern: keep the ring finger on E2 and move only index and middle when possible. This reduces motion and speeds transitions.
Arpeggio practice: play the strings D→G→B→E one at a time, holding the chord for four counts; then switch to the partial voicing and repeat. That locks the sound into your ear and your fingers.
Troubleshooting mistakes players make with B7 on baritone ukulele
Wrong fret placement: if the chord sounds sharp or buzzing, move fingertips slightly behind the fret and press just enough to avoid choking the tone; verify each string rings clearly one by one.
Muted B string: check finger angle — often the middle or index touches the B string unintentionally. Rotate the fingertip toward the thumb to free neighboring strings.
Muddy sound: if B7 sounds congested, try the 3‑note voicing (x–2–0–2) or move to a higher inversion; lighter finger pressure or slight positional shift toward the neck can also clarify tones.
Creative uses and genre-specific approaches for B7 on baritone uke
Blues & rock: use B7 as a turnback chord in quick two‑beat hits; add slides into the flat‑7 or hammer onto the third (D#) for grit. Try alternating full and partial voicings for a call‑and‑response feel.
Folk & pop: play sparse B7 voicings under vocals and use gentle arpeggios; letting the high B ring supports melody while the low end stays warm.
Jazz & bossa: add small extensions (B9 or B7b5) and use chromatic passing chords between B7 and Emaj7. Keep comping light and use syncopated chords to compliment a soloist.
Quick reference: fretboard map, chord diagrams (text), and learning resources
Textual fretboard map (common B and A positions): B positions — D9, G4, B0, E7. Flat‑7 (A) positions — D7, G2, B10, E5. Memorize these four spots for quick voicing work.
Chord diagrams (text): B7 open = D–G–B–E : 1–2–0–2. B7 partial = x–2–0–2. B7 higher inversion = 9–8–7–5 (D–G–B–E). B7sus4 = 2–2–0–2.
