C6(#11) Guitar Chord - Guitar Chords Chart
The C sixth sharp eleventh chord, written C6(#11), stacks root C, major third E, fifth G, major sixth A and sharp eleventh F#. Placed an octave up, the F# sits a half step below the fifth, G.
Use the C Lydian scale for melody: its raised fourth is the sharp eleventh of the chord. A natural eleventh would lie a half step above the major third and grind against it, so the raised version is used instead. For a visual route to the same notes, see how intervals sit on the neck.
