You can create a great wah-wah effect by simply bouncing the kalimba body on and off your belly as you play.
The Kalimba originally comes from Africa. It is a centuries-old instrument, also known as "Mbira" and "Sansa" or simply "thumb piano". There are metal reeds placed on a wooden resonance box, which are plucked with the thumbs to produce a metallically fine sound.
