Modes Lesson

The Dorian mode is the second church mode. It's the same as the natural minor scale (Aeolian mode), but with a raised 6th (major 6th) note.

The Dorian mode is spelled: 1 2 b3 4 5 6 b7 1

The best music theory lesson I've found on Dorian is this lesson by David Bennett Piano, shown below. Enjoy!
