About C6 — drop 3 voicings
C6 is C, E, G and A — C with a major sixth added on top.
It sounds warm, and finished without being sweet. It closes a tune as firmly as the triad does but without the maj7’s shine, which is why so many standards end on one.

Also written Cmaj6, CM6 or C major 6. The same chord either way; which spelling you meet depends on who wrote the chart.
How to play C6
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
C6 has 10 of them, on strings 6-4-3-2 and strings 5-3-2-1, from open position up to the 13th — every inversion the chord has: C in the bass, E in the bass, G in the bass and A in the bass. The one to learn first is the G shape at the nut.
5 of them sit on strings 6-4-3-2, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with x32210 — no barre and 1 open string. 1 of the 10 shapes here sits in open position. 4 of the 10 need a barre. Together they cover the neck from the 1st fret to the 15th.
