Chord & FretC#13 — dominant thirteenth
Also written Db13 — the same chord, spelled the other way.
Notes in C#13: C# – E# – G# – B – D# – A#Formula: 1 – 3 – 5 – b7 – 9 – 13In 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 13 is the full extended dominant. In practice, the third and seventh define the function while the thirteenth gives the color — the root and fifth can be omitted.
The same chord on all four instruments
Where to use it: An elegant dominant in jazz, MPB and gospel.
