B6 Chord on Piano
B6 = B – D# – F# – G# (Root, Major 3rd, Perfect 5th, Major 6th)
B6 is built from B, D#, F#, G# — root, and the rest of the major 6th formula stacked above it. Play B6 and the character is immediately smooth, avoiding the leading-tone pull of a major 7th. On the keyboard B is the white key right after the three-black-key group, with no black key directly above it, and the chord itself is a four-note shape that usually falls under fingers 1, 2, 3, and 5 (or 1, 2, 4, 5) in one hand. It works as a tonic substitute in B major — many players use it in place of a plain I or Imaj7 chord to close a tune, and it's a resting chord, not a tension chord — the added 6th just enriches the color without pulling anywhere. With the root counted in, the full chord runs to 4 notes, a figure worth having ready when reading any written voicing.
The harmonic role here is a tonic substitute in B major — many players use it in place of a plain I or Imaj7 chord to close a tune, which is the situation you'll most commonly find it in. This shape asks nothing unusual of the hand in terms of span, which means the fastest path to fluency is simple repetition hands-separately before combining with a bass line. D# anchors first inversion once it's moved to the bass under the remaining notes — with a four-note shape, knowing the inversions isn't optional if you're reading real chord charts. You'll hear it worked into 1950s and 60s pop closing chords regularly, and it recurs in Great American Songbook standards, where a 6 chord is a classic tonic ending too. It's a resting chord, not a tension chord — the added 6th just enriches the color without pulling anywhere. Because B is white key right after the three-black-key group, with no black key directly above it, the white key sits in the most natural reach for the hand, needing no forward adjustment at all. With low end already covered by a bass instrument, keep the left hand light — root, maybe the 7th — and let the right hand's upper notes do the harmonic work. Where you place this shape on the keyboard changes its character more than almost anything else you could do to it — low and it punches like bass, high and it turns delicate. Recognizing B6 by ear usually comes down to that smooth, avoiding the leading-tone pull of a major 7th character sticking in memory, faster than memorizing the actual note names ever does.

How to Practice It
Right hand alone first: fingers whichever of 1-2-3-5 or 1-2-4-5 keeps your wrist level; both are standard choices for this shape, aimed at B, D#, F#, G#. The white-key root here is forgiving of hand position, so focus your attention on evenness of tone instead. Add a simple left-hand root underneath only once the right hand is reliable, and resist combining both hands before either one is solid alone. Once combined, loop the transition into B6 from a neighboring chord slowly, letting tempo increase only after the hand-shape change stops requiring conscious thought. It's easy to confuse the 6 chord with an inversion of the relative minor 7th chord, since they share three notes; listen for which note sits lowest in the bass to keep the function straight.
Common Progressions
- B6 closing a tune as a I6 tonic in B major
- I – vi – ii – V – I6, with B6 as the final chord instead of a plain triad
- B6 substituting for Imaj7 in a jazz-standard-style turnaround
FAQ
- What notes make up B6 on piano?
- B anchors B6 as the root, with D#, F#, G# completing the major 6th formula above it — together, B, D#, F#, G#. That's root position; inversions just change which of those notes lands lowest.
- Can B6's 4 notes be split between the hands instead of played together?
- In most cases, yes, one hand covers it comfortably — but splitting the root off to the left hand is common practice too, not a sign you're doing it wrong.
- What role does B6 tend to fill in a chart?
- The short answer: a tonic substitute in B major — many players use it in place of a plain I or Imaj7 chord to close a tune. It's a resting chord, not a tension chord — the added 6th just enriches the color without pulling anywhere.
- What's the closest related chord to B6?
- Raise the 6th a half step and it becomes the 7th of a dominant chord instead — the 6 chord and the 7 chord share three notes but resolve completely differently.
