About the Diagram
What image comes to mind when you think of the harmonica? Maybe you picture a scene from an old movie with a hobo or convict slumped against a wall playing a sad, lonely tune or you see a blues musician on stage giving it all he's got to produce the most incredible riffs . Either way, you're hooked on the sound. The harmonica (aka harp) is a simple instrument capable of producing a wide variety of sounds and it fits in your pocket so you can take it anywhere.
