Question

How do you appreciate efforts of a musician to produce melodious sound using a musical instrument by simultaneously controlling frequency and amplitude of the sounds produced by it?

Answer 1

Hint:
To distinguish between music and noise one should posse’s knowledge of pitch. The quality of sound is best determined by the pitch of sound. Also, one should have knowledge of nodes and antinodes.

Complete step by step answer:
The difference between the qualities of two musical sounds produced by two musical instruments is basically due to the shape of the sound waves produced and the waveform of the sound wave. All the music is created by standing waves through the instruments. Standing wave is created by two waves of equal wavelength and frequency reinforced on each other. When two waves are reinforced then energy looks like standing waves. Standing waves occur in all wave mediums and can be said to be present in resonance. Frequency is speed of sound and amplitude is loudness so if the music is of appropriate loudness and frequency one can distinguish between two sounds.

Note:
The loudness of the sound is dependent on the amplitude, that is as the amplitude increases the loudness of the sound increases and the pitch of the sound depends on the frequency that is as the frequency increases, the pitch of the sound also increases.
