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.
Tap any note on the neck.
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.
What is C# Aeolian?
C# Aeolian is the seven notes C# D# E F# G# A B — the notes of E major started from its 6th degree, C#. Same seven notes as the parent, but with C# as home, so the intervals and the sound are different.
C# Aeolian vs C# natural minor
They are the same seven notes in the same order. “Aeolian” is the mode name for the natural minor scale — it says which chord you treat as home, not that any note changed.
Chords in C# Aeolian
Stack the mode in thirds and each degree becomes a chord. The home chord is C#m; the rest are the chords of E major, since the notes are the same — what changes is which one the music rests on. Vamp between C#m and A and the mode is unmistakable.
C# Aeolian on the guitar neck
Because C# Aeolian is E major from its 6th note, its natural fingering is position 6 of the seven three-notes-per-string shapes of E major — the shape whose lowest note is C#. Learn that shape with C# as home — start and end on it, over a drone on C# or the vamp above — and you have the mode under your fingers. Play the same shape with E as home and you hear E major instead. The other six positions are the fingerings for the other six modes of the same key.
How to practice C# Aeolian on guitar
- Loop position 6 of E major at 60 BPM, starting and ending on C# so your ear hears C# as home rather than E.
- Hold a C#m chord (or record one) and play the shape over it. Listen for the chord tones landing on the beat.
- Hear it harmonized in 3rds on the Fretboard: press Play and every note sounds with its partner while the neck lights up.
The tool draws C# Aeolian from its own root: the orange dots are on C# and the degrees count from it. The notes are its parent key's, E major; to hear Aeolian, start and end on C#.
