Quality of a musical note depends on – (1) Fundamental frequency (2) Amplitude of the wave (3) Harmonics present (4) Velocity of sound in the medium
by

1 Answer

Answer :

(3) Harmonics present Explanation: Sound "quality" or "timbre" describes those characteristics of sound which allow the ear to distinguish sounds which have the same pitch and loudness. Timbre is mainly determined by the harmonic content of a sound and the dynamic characteristics of the sound such as vibrato and the attack-decay envelope of the sound. Harmonic content is the most important of these.
