The lowest shape sits at fret 2 and spans 3 frets, with no open strings in it. The E and B strings stay silent, so 4 of 6 sound. C falls on the A string. It sounds from C3 up to G#4. 2 voicings are charted, the highest starting at fret 8.
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 C 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.
