This how to video is overview of the same mode played in different positions on the harmonica. As you can hear there are better positions for the tune "Help Me" than other positions. For example the C harp in 4th sounds the worst because of the unstable root. Even though this tune is traditionally played in 2nd position (cross harp) I prefer to play it on a G harp in 3rd position because I think it offers more sonic options due to it's naturally occurring Dorian mode.
