Reference Scale:


  1 2 3 4 5 6 7 8 9 10 11 12 1'
Note C C# D D# E F F# G G# A A# B C
Note C Db D Eb E F Gb G Ab A Bb B C

Use this table to construct the mode starting on any note, using the pattern of intervals below.

Aeolian Mode:


  I   II   III   IV   V   VI   VII   VIII
    Tone   Semitone   Tone   Tone   Semitone   Tone   Tone  
Note A   B   C   D   E   F   G   A

This pattern of intervals: T-S-T-T-S-T-T* is the characteristic of the Aeolian mode, and forms the modern natural A Minor scale (relative minor of C major).

Because the mode is characterised by its interval structure, you can start on any note and progress with the same intervals to produce an Aeolian mode in that 'key'.

This would be 'D Aeolian':

  I   II   III   IV   V   VI   VII   VIII
    Tone   Semitone   Tone   Tone   Semitone   Tone   Tone  
Note D   E   F   G   A   Bb(A#)   C   D

* T = Whole Tone, S = Semitone
