Short answer

Dominant eleventh chords sound wide and suspended. The eleventh sits a half step above the major third that would normally anchor the chord, a clash sharp enough that the third is left out entirely and the fifth, seventh, ninth and eleventh do the talking.

How to use the B11 chord

The B11 chord is built from a root, a perfect fifth, a minor seventh, a major ninth and a perfect eleventh. Start at the root B and stack the intervals to get the whole chord: B, F♯, A, C♯ and E. The same formula gives you the chord in any other key.

Dominant eleventh chords show up in modal jazz and gospel as a suspended, unresolved colour, often standing in for a sus4 with extra shimmer on top. They work best in slow-moving vamps rather than fast cadences.

Where B11 is used

A dominant chord wants to resolve. Its home is the V of a major key - and the I of a blues, where the pull never lets up.
