Hands for Tonal Change while Chugging

Here's a simplistic, but effective way to incorporate your hands while playing. Go to http://www.bluesharmonica.com/lessons/solo_harmonica_study_2 and study Ex. 1.5. While playing single notes, open your hands. When playing chords, close your hands (cupped). Playing this way emphasizes the melody (louder and brighter in tone) and de-emphasizes the chording (softer and more muted/bassy). This accentuates the impression that two harmonica players are playing.
