Why are musical instruments first warmed up before performing?
Ans: When musical instruments are used for
performance, either pipe type or string type or the layers type, they
are in motion or are exposed to slightly high temperature of exhaled air
or hand or anything else. The frequency of music generated corresponds
to that temperature.
When the device is first used after a long period of rest or
abstinence, the temperature of the device will be equal to that of the
environment, i.e. colder than the performing temperature. So, this will
decrease the velocity of sound as well as the frequency produced. Such
phenomenon is defined as the device going ‘flat’.
In order to prevent this, they should be warmed up for few minutes,
bringing the temperature to the performing level and then brought to
use.
