Chord & Fret

A/C# — with the third in the bass (first inversion)

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

Notes in A/C#: C# – A – EFormula: 1 – 3 – 5 / 3

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.

C/E is the C major chord with E in the bass — the first inversion. The harmony is the same, but the bass becomes lighter and gains melodic direction.
