THE ROLLER CANARY IOI 
Schockel belongs to the category of Bell tours; in 
fact, it is a deep hollow bell. Many breeders confuse 
it with the medium-pitched hollow bell, which also has a 
Schockel-like (rocking) effect, but this not true Schockel; 
it lacks the deep, soul-stirring melody. 
Schockel has its faulty variations. In consequence 
of its depth and its full structure, it creates a strong 
demand on the bird’s song apparatus, and if this lacks 
the required amount of strength and vigour to produce 
the depth of tone we may get Schockel that is weak, thin, 
or nasal. We sometimes hear men speak of laughing 
Schockel, which, however, is a degenerated variety, the 
ground note being “a.” 
Schockel must not be confounded with the tremolo 
roll tours. In the latter we have rolling, quivering, 
trilling tones; in the former, we have an articulation 
backwards and forwards, a swinging, waving movement 
of the song syllables. Here we would repeat the old 
illustration—namely, Bell, Hollow Bell, and Schockel 
represent three bells, a small tinkling bell, a medium- 
sized one, and a deep-toned bell. To correct any doubt 
as to what is a bell tour and what is a roll, it might help 
to keep the following adage in mind: “‘ what rings does 
not roll, and that which rolls does not ring.”
