A Dim Chord on 12-String Guitar
Play A Dim on 12-String Guitar: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The A Dim chord is a diminished chord built from stacked minor thirds, often used as a passing or leading chord. It is built from the notes A, C, D#. This page shows how to play A Dim on 12-String Guitar with clear fretboard diagrams and suggested finger positions.
The shape nearest the nut leaves the A string open and takes the rest at fret 1, reaching across 2 frets. 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.
