B6 Piano Chord
B6 is the B sixth chord. It has four notes: B, D sharp, F sharp and G sharp. Three of the four are black keys; only the B itself is white, so the hand plays one white key and then climbs onto the black ones.
B at the bottom under the thumb, then D sharp, F sharp and G sharp, all black. Right hand 1-2-3-5, left hand 5-3-2-1.
How to play B6 on piano, step by step
- Start on the B below middle C. That is the lowest note of the chord.
- Thumb (1): B
- Index finger (2): D♯
- Middle finger (3): F♯
- Little finger (5): G♯
- Press them together with the right hand. The left hand plays the same notes with fingers 5, 3, 2, 1 an octave lower, or just B on its own as a bass note.
The thumb takes the white B and the other three fingers sit entirely on black keys: D sharp, F sharp and G sharp. Keep the hand well into the keyboard so the upper fingers reach the black keys without straightening.
Inversions of B6
The same 4 notes with a different one at the bottom. All of them are B6; which you play depends on what the hand is coming from. Tap any card to hear it.



If it sounds wrong
- The top note slid onto A
- Falling from G sharp onto the white A gives a B7 sound, which pulls toward E. The sixth is the black key G sharp, one whole step above F sharp.
- It sounds like G sharp minor
- B6 shares its four notes with G#m7. When G sharp sits lowest the chord reads as minor. Keep B at the bottom, or put a low B in the left hand.
- The white B is buried
- One low white key under three raised black ones is easy to underplay. Give the thumb a little extra weight so the root actually leads the chord.
What makes it a B6
B · D♯ · F♯ · G♯ 1 3 5 6
B6 is a B major triad, B, D sharp and F sharp, with a G sharp added: the sixth, a whole step above the fifth. The triad stays intact, so the chord keeps B major's brightness with an older, softer top note.
Counted from G sharp, the same four notes spell G#m7, the relative minor seventh. The bass note picks the name. That closeness is why B6 moves so easily into G sharp minor territory without the hand travelling anywhere.
B6 vs Bmaj7
One black key apart at the top. B6 adds G sharp, a whole step over the F sharp; Bmaj7 adds A sharp, a half step under the B above. G sharp lets the chord rest; A sharp leaves it shimmering.
Hold B, D sharp and F sharp, and swap the little finger between G sharp and A sharp. The first sounds like the end of a rockabilly tune, the second like the start of a slow one. Same hand, different centuries.
Questions about B6
Is B6 the same as G#m7?
Same four notes: B, D sharp, F sharp and G sharp. B in the bass makes it B6; G sharp in the bass makes it G#m7.
What fingers do you use for B6?
Right hand: thumb on B, index on D sharp, middle on F sharp, little finger on G sharp, which is 1, 2, 3, 5. Left hand: 5, 3, 2, 1.
What is the difference between B6 and B7?
B6 adds G sharp, a colour note with no pull. B7 adds A, a flat seventh that drives toward E. One is an arrival, the other a departure.
How many black keys are in B6?
Three: D sharp, F sharp and G sharp. Only the root, B, is white, so the hand sits mostly on the black keys.
When would I use B6?
As a warm final chord in B, and under melodies that rest on G sharp. Guitar keys like B bring it out in rockabilly and old rock and roll piano parts.
