The Travelimba is a new world percussion instrument that has two different playing surfaces. It has an eight inch diameter and produces a big sound for such a small instrument. On one side is an eight note marimba and a wood head on the other. They come in different thicknesses. The thicker the shell the deeper the tone. You can hold the travelimba and play it or you can set it on a snare drum, tom tom or table and you will get slightly different sounds. The package includes the travelimba, a pair of rubber ball mallets and a drawstring case.
