Drawing a bow across a violin’s strings causes them to vibrate. But the vibrations of the strings aren’t strong enough to create very loud or musical sounds.

The body of the violin is a sound box and it vibrates, too, creating a rich, round sound and amplifying it. (Artem Furman/ Shutterstock) Read More
