C Dominant Thirteen Sharp Fifth Guitar Chord Fingering
C13#5 is the symbol for the C thirteenth sharp five chord, which contains C, E, G#, Bb, D, F and A (root, major third, raised fifth, minor seventh, ninth, natural eleventh and thirteenth).
Here the fifth is raised by a semitone, so G# stands where G would be in a plain dominant chord. The major third E and the minor seventh Bb give the chord its dominant identity.
The natural eleventh F sits a half step above the major third E, and that close neighbour is part of what makes the chord dense.
C 13th with sharp 5th guitar chord is also written as C13(#5), C13#5 or C13+5.
