Question

Note is a sound:
A) of mixture of several frequencies.
B) of mixture of two frequencies only.
C) of a single frequency.
D) always unpleasant to listen to.

Answer 1

Hint: Note is used to represent which class of any music-sound. Pitch is the duration of musicians found in musical notation. The note term is used to denote sound or musical sound.
If we used to sound two frequencies to make a note that it is the integer’s power of both two frequencies. By the help of note-musical notes system which is known as Octave is formed. Notes can be written as words and after reading these notes we can easily remake the original sound.

Complete step by step solution:
Sound waves are propagating in any medium in a longitudinal way because sound waves are longitudinal in nature. Hence if frequency and wavelength is also associated with this sound wave. On the basis of frequencies sound can be recognised by two ways-
1. Tone: The sound or sound wave associated with a single frequency is known as tone of the sound as an example if a person speaks a word like mango so it is considered as a single frequency sound or tone.
2. Note: A sound or sound wave associated with several different frequencies is known as multiple frequency sound or not as an example if a person sings Happy Birthday song and sound waves become a mixture of several frequencies.

Hence option (A) is correct.

Additional information:
Notes in a music system can be written on a paper by which another person can easily produce the same sound which is discovered by any person. In Indian culture there are 8 notes which are known as Octave. These Octaves are sa, re, ga, ma, pa, dha, nii, saa. With the help of these Octaves we can easily make a sound that is pleasant to listen to.

Note: It is clear that when a tone is produced we can easily recognise the source by which sound is produced but in the note we cannot recognise the original source by which the sound is produced and we can also copy the note of any sound.
