The structure gives us the most essential character- 
istic of each tour, and the study of this renders it easier 
for the breeder to recognise and name the tour. The 
musical value of a tour lies in the quality of its tone, and 
judges award points accordingly. Tours are good or 
faulty, according to their tone quality.
