Shape characteristics
Partial barre
One finger presses two strings at the same fret. A lighter, less tiring grip than a full barre while still being fully movable.
Mid-neck · fret 7-9
Balanced tone, with neither the ringing openness of first position nor the bright snap of the upper register. Common choice for rhythm work when you want a fuller, more compact sound.
Full six-string voicing
All six strings ring, giving you the biggest, most resonant version of this chord, ideal for strumming and solo acoustic contexts.
Bass: B · Top: C♯
The 7th (or equivalent upper tone) is in the bass, producing a suspended, leading quality that naturally wants to resolve downward.
