Re: why it that two violins sound the same as one violin?

the difference in sound is understood when they are either of different
frequency or amplitude or both.the difference in amplitude only makes one
differentiate in terms of loudness.
the quality depends on frequency.the first string of violens are adjusted
to a standard frequency by adjusting the tension.the other strings tensions
are adjusted takin the first one as base.thsu when the sound same they r
playin at the same frequency producing same sound quality due to
constructive interference.
