C#maj11 — major eleventh

Also written Dbmaj11 — the same chord, spelled the other way.

Notes in C#maj11: C# – E# – G# – B# – D# – F#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.

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.
