80 THE ROLLER CANARY 
have the tour described as slow, hammering, etc.; 
nevertheless, if these forms are sung pure, the tour may 
be classed as fair. Hollow Bell is faulty when the key 
vowel does not ring true, and borders on e or 4. When 
nasal, it may be dangerous. 
Hollow Bell should come between Bell and Schockel 
on the register, and in this position it is reckoned as a 
good tour. Its range is greater, and its tonality better 
than that of simple Bell, and it should therefore score 
more on the judging standard. 
SCHOCKEL 
The ground tones of Schockel are the same as Hollow 
Roll, deep ti, 0, u, also a, a, 6, e. The consonants are 
h and 1, occasionally g and b, ho-ho-ho, hu-hu-hu, 
hii-hu-hu, lo-lo-lo, lu-lu-lu, li-li-lu, etc., etc. 
Schockel cannot be confused with Hollow Roll, for 
it does not roll; the “‘r” is entirely absent. The trilling 
tour Hollow Roll does not ring out its notes in separate 
beats like Schockel, but pours forth a roll in tremolo 
form, and, therefore, one should not be mistaken for 
the other. In Schockel, the purity of the vowel is the 
measure of the quality; the consonants are of less im- 
portance. It is best sung on pure u, 0, U; on a it is not 
so good, tending, as it does, towards flatness. On 6, e 
and a it is apt to degenerate into the nasal. The con- 
sonants h and | are, as a rule, only slightly audible, whilst 
g and b have a somewhat angular beat. Most of the 
faults in Schockel occur in the vowel section, and incline 
to nasal. 
Bell has been likened to the tinkle of a tiny bell,
