Chord & FretBbmaj11 — major eleventh
Also written A#maj11 — the same chord, spelled the other way.
Notes in Bbmaj11: Bb – D – F – A – C – EbFormula: 1 – 3 – 5 – 7 – 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 maj9 stretched to the eleventh. Since that note brushes against the major third, arrangements usually keep the two octaves apart — or swap it for the sharp eleventh.
The same chord on all four instruments
Where to use it: Modal jazz and keyboard arrangements; more of a texture than an arrival chord.
