Brief video exploring the character of the dorian mode by playing some dorian melodies first in dorian and then in the natural minor.
The dorian mode differs from the natural minor only by one note, so was interested to see how changing that note affected the character of the melodies. In dorian, the 6th note is major, whereas the natural minor's 6th is minor.
A lot of the songs written in dorian seem to exploit this characteristic. Possibly also because the major 6th gives you a major dominant (V) chord in the scale, which otherwise would be minor.
