Chord & FretAm(maj9) — minor major ninth
Notes in Am(maj9): A – C – E – G# – BFormula: 1 – b3 – 5 – 7 – 9In 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 minor major seventh, now with the ninth. It keeps the same suspense — the friction between minor third and major seventh — and the ninth makes it wider and less sharp-edged.
The same chord on all four instruments
