What B Half-Diminished Is

The B Half-Diminished is a half-diminished seventh chord — a diminished triad plus a minor seventh, with interval membership [0,3,6,10]. It commonly functions as the ii chord in a minor-key cadence.

How B Half-Diminished Sounds

The B Half-Diminished has the dark, suspended character of a half-diminished seventh chord. The diminished triad supplies instability while the minor seventh makes the chord less symmetrical than a fully diminished seventh, giving it a clear root and a strong pull toward the dominant in a minor key.

How To Use B Half-Diminished In A Progression

Half-diminished seventh chords most commonly function as ii in a minor-key iiø-V-i cadence. The diminished fifth and minor seventh prepare the dominant while preserving a distinct root, and smooth voice leading then carries those unstable tones into the dominant and onward to the minor tonic.

Playing B Half-Diminished On Guitar

On guitar, the most common voicings of B Half-Diminished use the open position when possible (which is why guitarists tend to favour keys like E, A, D, G, and C) and movable barre or half-barre shapes everywhere else. The voicing diagrams above show several practical positions across the neck — the open or low-fret voicings will sound brightest, while the higher voicings will have a thinner, more focused tone. Always experiment with which fingering serves the line you are playing.
