Andy, a site I was at seemed to indicate that Soprano and Standard were the same thing.Baritone = Largest and most bass
Tenor = Larger size and more bass
Concert = Slightly larger size
Standard = small body little bass
Soprano = Smallest body, hardly any bass
According to them there are only 4 types.
Soprano often refereed to as Standard = Smallest body, hardly any bass
Concert = Slightly larger than Soprano/Standard
Tenor = Larger size and more bass
Baritone = Largest and most bass
Have you seen this before or is that site all wet?
