Aaarrhgg ye matey! Thar be some good physics!

The Iolani water polo team went to California to play over spring break. On our one day not playing polo we went to Disneyland. This is a picture of a pirate band on the street. 

Vibrations create waves and those waves carry energy and information. When the pirates play the keys of their piano thing and violin, they are creating vibrations in the keys and strings of their instruments. The vibrations of the strings in their instruments create sound waves that move through the air. However, the sound created by these waves is much to soft to hear, unless your ear is right next to the strings, especially in the loud environment of Disneyland. So, the body of the violin and the piano thing are there to amplify the sound. The vibrations of the strings cause the bodies of the instruments to vibrate, thereby increasing the vibrating surface area that is in contact with the air, so more waves are being created and everyone can hear! Aarrgh! That be sounding like good physics to me!
