The A# 7b5 chord is an extended or altered dominant that stacks ninths, elevenths, thirteenths, or chromatic tensions over a dominant-seventh core. It is built from the notes A#, D, E, G#. This page shows how to play A# 7b5 on 12-String Guitar with clear fretboard diagrams and suggested finger positions.
The D and E strings ring open in the lowest shape, with the remaining notes fretted at fret 1. The E and B strings stay silent, so 4 of 6 sound. A# falls on the A string. It sounds from A#2 up to E4. 2 voicings are charted, the highest starting at fret 6.
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.
