Symphonic musicians always “warm up” their wind instruments by blowing into them before a performance. What purpose does this serve?
Solution 5DQ The answer is because of temperature and moisture. In low temperature, it’s hard to reach the high nodes as the vibration will not be sufficient for different nodes. In cold the vibration is very less and the frequency and amplitude also get affected by this. So, by blowing, the instrument gets heated and they can play it easily with desired nodes. One more factor is the moisture. The instruments are very sensitive to the moisture in the atmosphere. So, the humidity also plays an important role but not as well compared to temperature. The dust particles sitting on the strings could also change many things, so by blowing air, they can get rid of this too.
