Play A m7b5 on 12-String Guitar: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The A m7b5 chord is a half-diminished (m7b5) chord, central to the minor ii–V–i. It is built from the notes A, C, D#, G. This page shows how to play A m7b5 on 12-String Guitar with clear fretboard diagrams and suggested finger positions.
The A and G strings ring open in the lowest shape, with the remaining notes fretted at fret 1. Both E strings stay silent, so 4 of 6 sound. The root is the A string itself. It sounds from A2 up to C4. 5 voicings are charted, the highest starting at fret 10.
12-String Guitar is strung in six courses of two, the lower four paired an octave apart, so each stopped note here sounds as two — which is why the shape rings thicker than the same grip on a single-strung instrument.
Browse alternate voicings to find the one that sits best under your fingers, then compare it with the other chord types built on A or explore the same shape in nearby keys. The diagrams list the notes in each voicing so you can connect the shape to the theory behind it.
