About C#maj11 — rootless voicings
C#maj11 is C#, E#, G#, B#, D# and F# — C#maj9 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 C#maj11
Leave the root to the bass player. In a band nobody misses it, and the ear supplies it from the guide tones anyway.
The finger it frees goes to a tension, which is why these sound richer than the shape they came from rather than thinner.
C#maj11 has 22 of them, on the top four strings, the middle four strings and strings 5-3-2-1, from open position up to the 13th — every inversion the chord has: E# in the bass, G# in the bass, B# in the bass, D# in the bass and F# in the bass. The one to learn first is the E# shape at the nut, which is the easiest grip here.
8 of them sit on the top four strings, 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 x43522 — no barre and down at the nut. None of the shapes for C#maj11 uses an open string, so every one of them is movable; the lowest sits at the 2nd fret. 3 of the 6 need a barre. Together they cover the neck from the 2nd fret to the 13th.
