Why does the tone of an instrument change by the temperature change?

Question

(clarinet). Is it because your body heat and the instruments are colliding together so it pushes out a wierd sound and that's why it's off key??

Answer 1

coz they expand and the vibrations change

Answer 2

Because the notes are determined by exact measurements.

All things swell with heat and shrink with cold (except only one thing, water..)  When you have a cold instrument the body is smaller than warm.  All orchestra instruments have to sit for a day before they will play them.

Answer 3

well things expand when exposed to heat or if exposed to a cold tempeture they tend to shrink. but for an instrument, depending what type your using, you always gotta tune it at whatever place you use it at. since i play guitar i gotta tune it every time i go somewhere cause if the place is hot then the strings tend to loosen up cause the strings expand due to the heat and vice versa to the cold tempeture.

Answer 4

The materials they are made of expand and contract depending on the temperature
