CHAPTER XI 
THE ROLLER’S SONG IN MUSICAL NOTATION 
HE natural song of the Canary has been changed 
i from its original form under the efforts of 
breeders and trainers who have in process of time 
developed and built up therefrom an artistic song full of 
charm and beauty. The natural gifts of the bird have 
been so successfully worked upon that the song to-day is 
a veritable triumph of art. 
To satisfy artistic requirements it may be laid down 
as a general axiom that as the song progresses higher and 
lower it should ring out harmoniously, and that during 
its course no disagreeable tones or phrases should appear. 
THE TOURS NOT UNDERSTOOD 
The tours of the Roller Canary seem difficult mostly 
because they require thorough discussion and classifica- 
tion, and this is seldom done. The main problem is 
that very common factor—variation. The Roller Canary 
is no different in its inheritance to man. One man sings 
deep bass, another light-bass, another deep baritone, 
another light-baritone, another tenor, and so on. This 
voice problem is a matter of register and confounding to 
the novice who does not know whether a “ tenor ”’ bird 
is singing Schockel because his deep-voiced bird is 
singing his hollow bell in a very similar key. 
There are other factors to be taken into consideration,
