How to Make Wah-Wah Sounds on Harmonica
This resonating harmonica cupping device produces a unique, affected “wah wah” sound which is not available using typical hand cupping methods alone.
The Harp Wah™ is not intended to take the place of your regular hand cupping techniques on the harp. This product, which is actually the first non-attaching “cup mute” for harmonica, was designed to add a whole new sound dimension to your harmonica effects.
Think of it in the same way a trumpet player uses a mute. Used in the right place, it’s a sparingly used, but indispensable sound effect to horn players.
