How do I read the chord diagram?

Strings run from the lowest (left) to the highest (right) – tick “Left-handed” to mirror it. Rows are frets; a number at the side shows the starting fret. Dots are fingers (1 index, 2 middle, 3 ring, 4 little), a long bar is a barre, × means don't play that string and ○ means play it open.

Why is a note missing from some C6 shapes?

On a fretted instrument you can't always play every note of a 4-note chord. The fifth (G) may be dropped – the chord keeps its character without it.

How is the C6 chord written?

The chord symbol is C6, and its full name is C sixth.
