C#11 — dominant eleventh

Also written Db11 — the same chord, spelled the other way.

Notes in C#11: C# – E# – G# – B – D# – F#Formula: 1 – 3 – 5 – b7 – 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 dominant stretched to the eleventh. In practice the third steps aside, because it and the fourth clash a semitone apart; what remains is a wide, almost suspended chord.

The same chord on all four instruments
