Bmaj9(#11) — major ninth sharp eleventh

Notes in Bmaj9(#11): B – D# – F# – A# – C# – E#Formula: 1 – 3 – 5 – 7 – 9 – #11

In 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.

Take a maj9 and add one unexpected note — an F# over a C chord — and the sound takes on the floating shine of a film score. That color has a name: lydian. The note is raised on purpose, because the plain eleventh would rub against the major third in a semitone clash.

Where to use it: Dreamy by nature, it opens or closes film-like ballads and modern jazz pieces. It is worth trying in place of a final maj7 when you want the music to end hanging in the air.
