Question
How do you account for the fact that two strings can be used to give notes of the same pitch and loudness but of different quality?
✓

Answer

If the two strings are plucked at different places in the same way and their lengths are adjusted such as they give notes of the same pitch and loudness, their waveforms will differ. Hence they will be of different quality.
