From the oldest family of music instruments, the tongue drum is a simple instrument with an amazing sound. Technically, it’s not a drum, as there is no vibrating membrane. It is instead classified as an idiophone (though somehow the word isn’t in the dictionary), as the tongue drum makes its sound through the vibration of the body when struck by mallets or played by hand.

For thousands of years, tongue drums were made to have just one or two slits and more closely represent what is now called the slit drum. These days, tongue drums are typically made to have anywhere from 4 to 16 notes, and usually have their own unique tuning.
