Question

How are different sound notes generated in musical instruments like guitar, which uses strings for sound generation, and flute, which uses blown air for sound generation?

Answer 1

Sound waves of different frequencies produce different sound notes. In the field of music, various musical instruments are used for the creation of sound notes. This includes instruments like sitar, violin, and guitar, which use strings for the production of sound and instruments like flute, and shehnai, which use air blown into pipes for the production of sound.

In string-based instruments, the frequency of vibration of the string is changed by changing the tension on the string and/or by changing the vibrating length of the string using fingers. This results in the generation of different notes.

In musical instruments like the flute, the holes on the flute are opened or closed to change the length of the vibrating air column in the flute. The frequency of waves, therefore, changes and it results in the production of different notes. In a flute, different notes can be generated by changing the way of air-blowing also.
