How to Play the C Dorian Mode
Practice the C Dorian Mode hands separately at a slow, steady tempo before putting them together. Aim for even rhythm and a relaxed wrist — the goal is a smooth, connected line where every note sounds the same length and volume. Once both hands feel comfortable on their own, layer them at the same slow tempo and only speed up when the joined version is clean.
Right Hand (RH)
Place your right hand over the keys with the thumb on the root. Use the fingering: 1-2-3-1-2-3-4-5 — 1 = thumb, 2 = index, 3 = middle, 4 = ring, 5 = pinky.
Watch for the thumb tuck: the thumb (1) passes under your fingers at note 4. Keep your wrist level and quiet — only the thumb moves under, the hand stays in place above the keys.
Left Hand (LH)
For the left hand, start with your pinky on the root. Use the fingering: 5-4-3-2-1-3-2-1
Watch for the crossover: a long finger (3 or 4) crosses over the thumb at note 6. Lift the long finger over cleanly without disturbing the thumb. Descending the scale, the thumb will pass under at the same spots in reverse.
Practice routine
- One octave, ascending only, right hand alone — slow and even.
- One octave, ascending and descending, right hand alone.
- Repeat steps 1–2 with the left hand alone.
- Hands together, ascending and descending, at the same slow tempo.
- Two octaves hands together once step 4 feels comfortable.
- Increase the tempo only when the previous tempo is fully clean.
Key Signature
The C Dorian Mode draws its notes from Bb Major, so it is written with that key signature: 2 flats (B♭, E♭).
Order of flats
Flats are added in a fixed order — the reverse of the sharp order. Each new flat key adds the next flat on the list.

Common Tones
Common tones are the notes that two scales or modes share. Knowing which notes the C mode shares with its parallel modes (same root, different scale) helps with improvisation, modal interchange, and smooth voice leading. The more notes two modes share, the more closely related they sound — and the easier it is to slide between them in a solo or progression.

|---|---|---|
| C Phrygian | C – D – E♭ – F – G – A – B♭ – C | 8 / 7 |
| C Lydian | C – D – E♭ – F – G – A – B♭ – C | 8 / 7 |
| C Mixolydian | C – D – E♭ – F – G – A – B♭ – C | 8 / 7 |
