All around the world, people play musical instruments.

Other instruments are known in certain parts of the world.

One thing is the same for all instruments.

Most instruments fall into one of  four families: strings, woodwinds, brass, and percussion.

Let's compare instruments from the  orchestra with traditional instruments.

We will see how they are alike and different.

A string instrument makes music when its strings vibrate,

It is a traditional string instrument from China.

The shape of the violin  and the erhu are alike.

However, the instruments are different in one way.

A woodwind instrument makes music when air vibrates in a tube.

So are the panpipes, a traditional instrument played in Peru and other parts of South America.

The two instruments make similar sounds, but they are  different in other ways.

Flutes have one tube, while panpipes have many tubes.

Panpipes are usually made of a different material such as bamboo or cane.

Brass players make music by vibrating their lips as they blow air into the instrument.

The pitch, or sound, of the tuba is low when you hear it.

The sound of the didgeridoo is as low as the tuba's sound.

However, unlike the metal tuba, the didgeridoo is made of wood.

Also, the didgeridoo is not as curved as the tuba.

Percussion: The Snare Drum and the Djembe

Percussion instruments vibrate and make a sound when something hits them.

An orchestra snare drum and the West African djembe are both drums.

However, they are different in some ways.

Snare drummers use drumsticks to make a sound,

An orchestra snare drum is usually 15 centimeters deep,

but a djembe can be over 60 centimeters deep.
