Question

why do different insrument have different sound qualities​

Answer 1

Answer:

$\large\mathbb{\underbrace\purple{ANSWER}}$

This is because musical instruments do not vibrate at a single frequency: a given note involves vibrations at many different frequencies, often called harmonics, partials, or overtones. The relative pitch and loudness of these overtones gives the note a characteristic sound we call the timbre of the instrument.

Answer 2

Answer:

The main factor that causes different sounds in an instrument is the harmonic frequencies and overtones that an instrument outputs on notes, with other factors such as material affecting this factor. A vibrating string does not produce a single frequency, but a mixture of fundamental frequencies and overtones.

.Explanation:

An instrument creates sound when part of it vibrates rapidly. The column of air inside a wind instrument, the string of a string instrument, or the stretched skin of a drum all vibrate when played. This vibration produces sound waves in the air, which we hear as musical notes.
