Musical instruments are grouped into families based on how they make sounds. In an orchestra, musicians sit together in these family groupings.
The String Family: yes, the sounds of string instruments come from their strings. The strings may be plucked, as in a guitar or harp; bowed, as with a cello or a violin; or struck, as with a dulcimer. This creates a vibration that causes a unique sound.
The Percussion Family:most percussion instruments make sounds when they are hit, such as a drum or a tambourine. Others are shaken, such as maracas, and still others may be rubbed, scratched, or whatever else will make the instrument vibrate and thus produce a sound.
The wind family:those instruments produce sounds when air (wind) is blown inside. The sound happens when the air vibrates inside. Brass instruments are made of brass or some other metal. The musician's lips must buzz, as though making a "raspberry" noise against the mouthpiece.
