C# Dorian

The C# Dorian mode (also written Db) — C# D# E F# G# A# B — shown across the guitar neck.

Also written Db Dorian. Db and C# are the same pitch — C# is the spelling in common use.

Swipe the neck sideways to see the higher frets.

C# Dorian is the natural minor with one note changed — the 6, A#. That single note is what the mode sounds like; lean on it and the colour is obvious, avoid it and you are just playing minor.

The tool shows this from its parent key, B major, with C# marked as where Dorian begins, the same seven notes centered on B.
