Cmaj11 guitar chord
An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful.

About Cmaj11 — open string voicings
Cmaj11 is C, E, G, B, D and F — Cmaj9 with the eleventh added — the note that fights the major third.
It sounds unsettled, and grittier than the rest of the major family. Most players drop the third or raise the eleventh instead, which is how you arrive at a sus chord or at maj7♯11.

How to play Cmaj11
An open string left ringing against a fretted grip. It costs no finger, so it can sound a note the closed shape has none left for: a tension on top, or a pedal root underneath.
These belong to their key rather than to a shape: they cannot be moved up the neck. D, A, G and E have many; E♭ has a handful.
Cmaj11 has 6 of them, on strings 6-5-4-3-2-1, strings 6-5-4-3-2 and strings 5-4-3-2-1, from the 3rd fret up to the 5th — every inversion the chord has: C in the bass, E in the bass and D in the bass. The one to learn first is the E shape at the 3rd fret, which is the easiest grip here.
Start with x33000 — no barre and 3 open strings. 2 of the 9 shapes here sit in open position. 3 of the 9 need a barre. Together they cover the neck from the 1st fret to the 12th.
