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':
