A#6 Chord
1st Fret · A-String RootThe A-shape barre chord with one note moved. Index on the A string at fret 1 for B♭, then flatten the ring finger across the D, G, B and high e strings at fret 3 — that gives F, B♭, D and G. In a plain major barre the high e would sit back at fret 1; pushing it up two frets is the whole difference between A# and A#6. Mute the low E.
A#6 Chord
6th Fret · E-String RootThe jazz 6th grip — four notes, one per string, no barre. Middle finger on the low E at fret 6 for B♭, index on the D string at fret 5 for G (the 6th), pinky on the G string at fret 7 for D and ring on the B string at fret 6 for F. The underside of the middle finger mutes the A string and the fingers' pads keep the high e quiet. The 6th sits in the middle of the chord rather than on top, which is the close, warm sound of swing rhythm guitar.
A#6 Chord
8th Fret · D-String RootFour strings, rooted on the D string — the voicing for when the bass player has the low end. Index flat across the D, G and B strings at fret 8: that sounds B♭ on the D string and G, the 6th, on the B. Ring on the G string at fret 10 for F and pinky on the high e at fret 10 for D. It is the open D6 shape moved up the neck, with the index standing in for the nut. Mute the low E and A.
One note on top of a major chord
Start from B♭ major — B♭, D, F — and add G, the note a whole step above the 5th. Nothing is taken away, which is why B♭6 can stand in for a plain B♭ almost anywhere.
Same notes as Gm7
B♭6 and Gm7 are spelled with the same four notes. Put B♭ in the bass and it is B♭6; put G in the bass and it is Gm7. Every shape on this page keeps B♭ lowest, so let the root ring.
Use it as a home chord
A 6th chord is stable — unlike a 7th it does not pull anywhere. That is why jazz, swing and western swing so often end a tune on B♭6 instead of a plain B♭.
The boogie shuffle
Blues and rock and roll rhythm parts rock between the 5th and the 6th over the root: B♭ and F, then B♭ and G, back and forth. That shuffle is the 6th chord broken into two halves.
Slide the grip
None of the three shapes here uses an open string, so all of them slide. Move any one up two frets and you have C6; down one and you have A6.
About the A#6 or B♭6 Chord on Guitar
The A#6 or B♭6 chord is built from four notes: B♭ (the root), D (the major 3rd), F (the perfect 5th) and G (the major 6th) — formula 1 – 3 – 5 – 6. It is a B♭ major triad with one note added, the 6th, which sits a whole step above the 5th. Nothing is taken away, so the chord is still major and still settled; the 6th only softens it into the sweet, slightly vintage sound of swing, western swing, doo-wop and early rock and roll, where B♭6 is a favourite last chord. It is written as a bare 6 after the root letter, and occasionally as B♭maj6 or B♭add6 — all three mean the same chord. B♭6 also has an unusual twin: Gm7 contains exactly the same four notes, G–B♭–D–F, so the name depends on which note is in the bass. With B♭ lowest, as in every shape here, it is B♭6. Do not confuse it with B♭maj7, which adds the major 7th instead of the 6th, with B♭m6, which keeps the 6th but flattens the 3rd, or with B♭6/9, which adds the 9th on top as well. This page covers three voicings: the A-string root barre at fret 1, the E-string jazz grip at fret 6, and a four-string form rooted on the D string at fret 8. Every diagram is interactive and playable with acoustic guitar sound.

The 4 notes that form the A# or B♭ Major 6th chord and their role in the major scale.
Every major 6th chord follows this same formula — root, major third, perfect fifth, and the major 6th added on top (no 7th).
Frequently Asked Questions
Play x-1-3-3-3-3 — index on the A string at fret 1 for the root, and the ring finger flattened across the D, G, B and high e strings at fret 3. The high e carries G, the 6th. Mute the low E.
B♭, D, F and G — root, major 3rd, perfect 5th and major 6th. Spelled from A# that is A#–C##–E#–F##, which is why the chord is usually written B♭6.
Same four notes, different bass. B♭6 is B♭–D–F–G; Gm7 is G–B♭–D–F. With B♭ as the lowest note it is B♭6, which is how every shape on this page is voiced.
As a softer, sweeter B♭ major — the final chord of a jazz or swing tune, the home chord of a doo-wop progression, or anywhere a plain B♭ sounds too bare. It is stable, so unlike B♭7 it does not need to resolve.
