List:

One very important factor is that all unwound strings in each note are
of equal length, which provides for better tuning stability of the
unisons when humidity changes take place.

> concert could go on.
> 
> No. 2--Using single strings the scale designer can more easily change
> wire sizes.
> 
> No. 3--While stringing the wire length can be measured more precisely
> to control uniform coils.
