Think about STP (Standard Temperature and Pressure). What happens when a material is move to a higher temperature? -- gas, liquid, and solid usually expand (note: water is an exception). And, in a lower temperature, they contract. Can you remember a law that relates temperature, pressure, and volume of a gas?

The thickness of violin strings are not all the same. Thus, a change in temperature will affect each string differently. This is also why pianos must be retuned after moving.

Now, with a violin, the casing also responds to changes in temperature and humidity. And, what about the bow?
