The major scale has a bright, happy sound that is perfect for upbeat songs. The minor scale has a sadder, more introspective sound. The Dorian mode has a similar sound to the minor scale, but with a few key differences. Firstly, the Dorian mode uses a natural 6th instead of a flat 6th (also called tempo). Secondly, it has a raised 9th instead of a flat 9th (which gives it a brighter sound). Lastly, it has a raised 13th instead of a flat 13th (again, making it brighter sounding).
