The F 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 F, G#, B. This page shows how to play F Dim on 12-String Guitar with clear fretboard diagrams and suggested finger positions.
The B string ring open in the lowest shape, with the remaining notes fretted at fret 1 over a 3-fret stretch. F falls on the E string. It sounds from F2 up to F4. 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 F 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.
