why does a trumpet go flat when cold?
perhaps I don't know
shortening the horn should make it go sharp.
cold temperatures causes the metal to contract which affects intonation , humidity also will affect intonation.
Because the speed of sound in air is a function of temperature.
that makes sense. thanks govtmodel.
Here is a pretty good Wiki article on the speed of sound and temperatures affect.

I`m new to this site so I`m not sure what I`m doing. I wanted to find out why an Olds Ambassador-1973 had external springs on the valves. They weren`t inside like the ones I`ve seen before.

In addition to all of the above responces I would ask you if you have ever tried to write your name while freezeing cold? I would guess that you hand writeing skills went south! Same thing goes for your lips and playing hand. They do not like being cold anymore then the rest of you. Your posture and embochure all change with your mood and tempature as well. I was amazed at how well those musicians played outside the Capital for the inaguration. The woman playing the piano had on what I used to call wino gloves ie gloves with fingers cut off. To play so good in such weather was amazeing. This is why we always try to warm our instrument s before a show and at the very least sometimes stick your mouthpiece under your arm to keep it warm waiting to go on. This is why Ivory,Glass and later plastics have been used by those that play outside like marching band people in cold climates.
ANother good example of how the body does not like cold. Sit on a cold bleacher watching a game. Then when it is time to get more drinks jump upand jump down to the ground instead of takeing all the steeps. Chances are good that you got all kinds of tingling not so good feelings running up your leg from something that when warm you wouldnot even think twice about doing. All of your connective tissue though is now cold. So everything just about in nature no matter if made by nature or made by man contracts in the cold and behaves differently!
