Chord & FretBb11 — dominant eleventh
Also written A#11 — the same chord, spelled the other way.
Notes in Bb11: Bb – D – F – Ab – C – EbFormula: 1 – 3 – 5 – b7 – 9 – 11In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.
The dominant stretched to the eleventh. In practice the third steps aside, because it and the fourth clash a semitone apart; what remains is a wide, almost suspended chord.
The same chord on all four instruments
Where to use it: Gospel, soul and funk; a dominant that would rather wait than resolve.
