One way is to hold it under your arm and hit it using the flat of your hand. Another way (the way most people play it) is to sit on a chair and put the djembe at an angle away from you between your knees/legs and play it with both hands.
Very young children will also want to stand the djembe on the floor and hit it with their hands. This makes a more dampened sound. Think of the hole in the bottom of the djembe as its mouth - that's where most of the sound comes out.
Bearing this in mind, this djembe is large enough for a small child to lay it on the floor and sit on it like on a horse and then hit the skin with hands or beaters.
You can also use a small beater or two as long as you don't hit it too hard. It's also ideal for using fingers to tap out rhythms.
It can be played with the wooden drumstick supplied free with each drum. Coffee stirrers from coffee shops also work well, as will any lightweight stick. When using your fingers it's best to flick them quickly, so that they just touch the skin for an instant before bouncing off again.
