There are different kinds of instruments. The flute is a wind instrument. Like the sound of the wind, the music comes from moving air. Some wind instruments have holes for fingers. Others have buttons to press. Another way to make music is with strings. The violin is a string instrument. When you slide a finger overa string or pluck it, it makes music. You can also make music byhitting or shaking something that makes a sound. That's because most things make a sound when you hit them. An empty space inside the instrument makes the sound louder. These are percussion instruments. The drum is a percussion instrument.
