Sound behaves in certain ways ...

Air conducts waves that we call sound, when nerves of our inner ears receive them.


Shorter (faster) waves sound higher.


Longer (slower) waves sound lower.

Try an experiment!

Musical instruments behave in certain ways

The materials from which instruments are made vibrate differently.

 Different waves create different voices.
Hard materials sound one way; soft ones another. Thick materials sound differently than thin ones.
Flexible materials sound different than stiff ones. Wet materials sound different than dry ones.
Metal, wood, plastic, paper, rock . . . all sound different.

Musicians cooperate with each other, too.

Watching each other,

Listening to each other,


Taking turns and sharing,
(Listen to the instruments taking turns.)

We have lots of fun!

Playing music together helps us understand how to make peace.
