They have invented many different kinds of musical instruments for this purpose. Despite their diversity, however, musical instruments share certain similarities. - All musical instruments create sound by causing matter to vibrate. The vibrations start sound waves moving through the air. - Most musical instruments use resonance to amplify the sound waves and make the sounds louder. Resonance occurs when an object vibrates in response to sound waves of a certain frequency. In a musical instrument such as a guitar, the whole instrument and the air inside it may vibrate when a single string is plucked. This causes constructive interference with the sound waves, which increases their amplitude. - Most musical instruments have a way of changing the frequency of the sound waves they produce. This changes the pitch of the sounds. Show less
