Also written A#/D# — the same chord, spelled the other way.
Notes in Bb/Eb: Eb – Bb – D – FFormula: 1 – 3 – 5 / 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 C triad over an F bass. From the bottom up it gives an F with a seventh and a ninth: a wide subdominant with no weight down low.
The same chord on all four instruments
Where to use it: Subdominant pedals, intros and suspended moods in the accompaniment.
