Question

1) Why are instruments tuned before being played as a group? In which ways do musicians tune their instruments? 2) Given that sound waves consist of series of air pressure increases and decreases, what would happen if an air pressure increase from one sound wave was located at the same place and time as a pressure decrease from another of the same amplitude? Hints: Please Fill In The Blanks Correctly: 1) Instruments are tuned before being played as a group so that [blank]. Musicians tune their instruments by adjusting tensions or tube lengths which changes their instrument

Explanation / Answer

Instruments are tuned before being played as a group since, Instruments are designed to play specific notes. They must be tuned to get the correct notes. If not tuned, each instrument plays a different kind of notes and the music will not be effective. Instruments are tuned before being played as a group so that they play the same kind of tones. Musicians tune their instruments by adjusting tensions or tube lengths which changes their instrument’s pitch. These adjustments are made while playing and listening to a reference tone (e.g. A-440 Hz). The musicians know when they are in tune by the disappearance of the notes. Because of superimposition , an increase in air pressure from one sound wave will cancel out a pressure decrease from another of the same amplitude resulting in what is known as destructive interference. The result would be faded in the combined sound’s loudness.
