Left-hand Bmaj7: shapes and fingers
Finger 5 (little finger) always takes the bottom note. Keep the hand low, near middle C but below it: lower than that the chord gets muddy. Black keys: D# F# A# (finger 3, 2, 1). White keys: B (finger 5). Move the hand slightly in so the fingers on black keys do not slip.
| Position | Notes, bottom up | Fingers |
|---|---|---|
| Root position | B D# F# A# | 5 3 2 1 |
| 1st inversion | D# F# A# B | 5 3 2 1 |
| 2nd inversion | F# A# B D# | 5 3 2 1 |
| 3rd inversion | A# B D# F# | 5 4 2 1 |
Ways to accompany with Bmaj7
Each pattern uses only notes of Bmaj7, so none of them can sound wrong.
| Pattern | Notes | Good for |
|---|---|---|
| Block chord | B+D#+F#+A# | slow songs, ballads, the first week |
| Walk up the chord | B D# F# A# | linking chords, a bass that sings |
| Root and fifth | B+F# | driving rhythms, a strong open sound |
| Octave bass | B+B | a heavy bass under a loud melody |
| Shell: root and seventh | B+A# | jazz, leaves room for the right hand |
Bmaj7 → G#m7 → C#m7 → F#7 with a quiet left hand
Do not play every chord in root position: the hand would jump. These positions move one or two keys at a time.
| Chord | Left hand plays | Keys that stay |
|---|---|---|
| Bmaj7 | B D# F# A# (Root position) | starting chord |
| G#m7 | B D# F# G# (1st inversion) | B D# F# |
| C#m7 | B C# E G# (3rd inversion) | B G# |
| F#7 | A# C# E F# (1st inversion) | C# E |
Both hands on Bmaj7
Over Bmaj7, the safest right-hand notes are the chord notes B D# F# A#; scale notes between them work as passing notes.
If both hands play the same notes in the same octave the sound gets thick: leave a gap.
Practise left-hand Bmaj7
- Place finger 5 on B, then let the other fingers fall on D#, F# and A#.
- Go through the patterns in the order of the table: block chord; walk up the chord; root and fifth; octave bass; shell: root and seventh.
- Play Bmaj7 → G#m7 → C#m7 → F#7 slowly until the change happens without looking down.
- Last, add a simple right-hand note on top: the left hand should keep going on its own.
Short daily practice wins: the left hand learns by repetition, not by long sessions.

How do you play Bmaj7 on piano with the left hand?
Put finger 5 on B below middle C and play B, D#, F# and A# with fingers 5 3 2 1.
Can the left hand play just two notes of Bmaj7?
Yes: root and seventh, B A#. Root and seventh already say which seventh chord it is; the right hand adds the third.
Is the left hand the same as the right hand for Bmaj7?
Same notes, mirrored fingers: the right hand plays Bmaj7 with 1 2 3 5, the left hand with 5 3 2 1, because the little finger sits at the bottom.
Does a game count Bmaj7 if I play it low with the left hand?
In ChordRunner, yes: the game listens for the notes B, D#, F# and A#, not for a hand or an octave. Use a USB MIDI keyboard, or the microphone with a real piano.
Your instrument is the controller.
ChordRunner is a browser game that teaches piano and guitar chords: a chord appears on screen, you play it on a real instrument, and your runner jumps. MIDI keyboard or microphone, both work.
