B9(#11) Guitar Chord - Guitar Chords Chart
B9(#11) is the dominant ninth chord with a raised eleventh, also called B ninth sharp eleven, and it is made of B, D#, F#, A, C# and E#.
The E# may look odd, yet it is simply F, spelled that way so the chord stays a stack of thirds above B. From the root the intervals are 1, 3, 5, b7, 9, #11. Every note of the chord sits inside the B Lydian Dominant scale, which adds only a sixth, G#.
It resolves like any dominant, to the chord a fourth above B.
B 9th with sharp 11th guitar chord is also written as B9(#11), B9#11 or B9+11.
