About the eleventh chord
In theory an eleventh chord stacks 1, 3, 5, ♭7, 9 and 11. In practice the 3rd is left out: it forms a minor ninth with the 11th and the sound gets muddy. Without the 3rd, C11 has the same notes as C9sus4 (and, with the 5th gone too, it becomes B♭/C): a soft suspended dominant, common in soul, gospel, jazz and pop.
