The instruments of the orchestra are organized into families:
Strings – String Instruments use vibrating strings to make their sound. The violin is an example of a string instrument.
Woodwinds – Woodwind instruments are made of a long hollow tube of wood or metal. The sound is made by blowing air through a very thin piece of shaved wood called a reed, or across a small mouthpiece. The clarinet is an example of a woodwind instrument.
Brass – Brass instruments are wind instruments made of metal with a cup shaped mouthpiece. The tuba is an example of a brass instrument.
Percussion – Percussion instruments are played by being struck or shaken. A snare drum is an example of a percussion instrument.
