Barre & movable

On ukulele, “barre” is often a partial barre — index across two or three strings — not a full six-string clamp. This page is the technique: how to make one finger hold two or three strings down cleanly. What those grips are worth musically, and how far they slide, is Movable shapes.

Roll the index onto its bony edge. Buzz is normal for weeks. Thumb behind the neck.

How a barre actually works

A flat finger is the wrong tool: the pad has a soft dip in the middle exactly where a string needs support, which is why the middle string of a three-string barre is the one that buzzes. Four adjustments, in the order worth trying:

  1. Roll the finger slightly toward the nut so the harder edge beside the nail takes the strings, not the soft centre of the pad.
  2. Move closer to the fret. A barre a few millimetres behind the fret wire needs far more force than one right against it.
  3. Pull, don't squeeze. The thumb behind the neck and the arm's weight do the work; a pinch between thumb and finger tires out in seconds.
  4. Slide the finger along until the buzzing string sits under a firmer part of it. Every hand has a slightly different sweet spot; find yours once and remember it.

Check your work one string at a time: play each string of the grip on its own and listen for the dead one. Strumming the whole chord hides which string is failing.

Bb — the gateway major

Index covers E and A at fret 1; middle and ring fill G and C. Slide the whole grip up the neck to name new majors.

Bm — the gateway minor

Index barre across C–E–A at fret 2; pinky on G fret 4. Slide for other minors.

String-by-string check

Hold B♭ (3 2 1 1) and pick each string on its own, G to A. The two barred strings, E and A, are the ones to listen to: a dull E means the index is flat on its soft centre; a buzzing A means the index has slid back from the fret.

A|----------1--
E|-------1-----
C|----2--------
G|-3-----------

The full barre — four strings, four chords

Lay the index across all four strings at fret 2 and nothing else: that is Bm7, the open Am7 moved up two frets. Now leave the barre down and add one finger on the A string. Each one turns it into a different D chord, because the A string is where the C-shape keeps its root.

Bm7 2 2 2 2 · D 2 2 2 5 · Dmaj7 2 2 2 4 · D7 2 2 2 3.

A|-2-|-5-|-4-|-3--
E|-2-|-2-|-2-|-2--
C|-2-|-2-|-2-|-2--
G|-2-|-2-|-2-|-2--

This is the full barre worth owning first: every string under one finger, and the pinky free to change the chord. Move it to fret 4 and the same four are C♯m7, E, Emaj7 and E7.

Barres in a song

A barre only counts once you can land it in time. Two progressions, each with one barre among open chords. In F, B♭ is the IV and the only barre: F 2 0 1 0 · B♭ 3 2 1 1 · C 0 0 0 3 · F 2 0 1 0.

A|-0--0-|-1--1-|-3--3-|-0--0--
E|-1--1-|-1--1-|-0--0-|-1--1--
C|-0--0-|-2--2-|-0--0-|-0--0--
G|-2--2-|-3--3-|-0--0-|-2--2--

In G, the vi chord is Bm and the V can be the closed D: G 0 2 3 2 · Bm 4 2 2 2 · C 0 0 0 3 · D 2 2 2 5.

A|-2--2-|-2--2-|-3--3-|-5--5--
E|-3--3-|-2--2-|-0--0-|-2--2--
C|-2--2-|-2--2-|-0--0-|-2--2--
G|-0--0-|-4--4-|-0--0-|-2--2--

Two strums per chord. Form the barre on the last strum of the chord before it, not after the beat — the change happens in the air, not on the strings.

Building it over a week

Barre strength is a matter of weeks, not of trying harder today. A progression that works:

  1. Two strings first. Barre only E and A at fret 1 and strum those two. Nothing else. When both ring, add the middle and ring fingers to make Bb.
  2. Hold and release. Form Bb, strum once, lift the whole hand off, form it again. Ten times. Forming it is the skill; holding it is just endurance.
  3. Move it up. Play the shape at fret 5 or 7 first — the strings press down more easily up there, so you feel a clean barre sooner and know what to aim for lower down.
  4. Then put it in a change. F to Bb and back, slowly, one strum each. A barre you can only find from a standing start is not usable in a song yet.

Stop when your hand aches rather than pushing through it — two short sessions a day beat one long one, and a strained fretting hand costs a week. The map of what these grips become is on Movable shapes, where you can slide them and hear it.

Ready when

Move on when all of these are true on a normal day, not your best one:

  • B♭ and Bm ring on a string-by-string check, every string clear.
  • A full barre at fret 2 rings on its own, and you can add the pinky for D, Dmaj7 and D7 without lifting it.
  • F · B♭ · C · F and G · Bm · C · D at 80 bpm with no gap at the barre.
