C# Aeolian

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

Also written Db Aeolian. Db and C# are the same pitch, though spelling it from Db would need double accidentals (Db Eb Fb Gb Ab Bbb Cb), which is why C# is the name in use.

Swipe the neck sideways to see the higher frets.

C# Aeolian is the natural minor — same seven notes, same order. The mode name describes which chord you treat as home, not a different set of notes.
