Percussion instruments include drums, shakers and rattles. Drums are one of the oldest and simplest musical instruments.
To make a sound with a percussion instrument, like a drum, you have to hit or shake it. Hitting or shaking it sets up vibrations in the air and you make a sound.

Look at each of these instruments. Which of these have you seen and heard?

Some drums have a 'skin' stretched over the top. When you stretch the skin tightly, it makes the vibrations quicker.

The drums in the steel band are different sizes. When you hit the top of one of the drums the metal top vibrates and makes a sound. The air trapped in the drum makes the sound loud.
