Modal RunsC#11 Chord (Dominant 11th)
Dominant 11th stacks the 11th on top of dom9 — root through the flat 7th, 9th, and 11th — a dense, often-thinned-out extended chord. The notes of C#11 are C#, F, G#, B, D#, F#.
Rarely played with every note at once in practice (the 3rd and 11th clash a semitone apart); guitarists usually voice a partial version, root/7th/9th/11th, for a modern funk or jazz-fusion colour.

Every playable, root-in-the-bass grip standard tuning offers, computed from the chord’s own formula — not a fixed shape library.
Try dropping the 3rd entirely — the resulting voicing (root, 7th, 9th, 11th) is the version that actually gets played.
