उत्तर
Quality of sound of the same pitch differs when produced by different instruments because of the difference in their waveforms. Different instrument emit different subsidiary notes due to the presence of mixture of subsidiary vibrations along with the principal vibration. The subsidiary vibrations present in the musical note make the wave form complex and thus we can easily distinguish between the sound so different instruments, though they may be of same pitch.
