Chord & Fret

C#/D# — with the ninth in the bass

Also written Db/Eb — the same chord, spelled the other way.

Notes in C#/D#: D# – C# – E# – G#Formula: 1 – 3 – 5 / 9

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 C triad over a D bass. Heard from the bottom up it is a suspended chord — a D with a fourth and a seventh, no third: open, and saying nothing about major or minor.
