THE ROLLER CANARY 73 
If other than these three consonants appear in these 
high notes, such as “‘ dschri,” we get Schnetter Schwirre, 
one of the most dangerous faults in the Roller song. 
BELL ROLL 
Composition: The ground tone is “i,” and the 
thinner sound “u.”” The consonant is “ r. 
The word “roll ’’ denotes the character of this tour, 
and “bell”? shows the position it occupies on the 
musical scale. This tour therefore occupies the same 
position on the register as Bell in contrast with the 
deeper rolling tour Hollow Roll. 
The idea that Bell Roll is so-called because it tinkles 
and rolls at the same time is incorrect, for a pure Bell 
Roll is sung in one continuous series “riririri,” or 
“rurtrtrt,” whilst Bell is discontinuous (for lack of a 
better word), and does not roll. 
Its quality depends upon the purity of the vowels 
Nig eae ” and the force of the “r.” The vowel 
” 
i and ty 
must be nicely rounded so as to manifest tonality; the 
“r?? must not drown the vowel. The tour is of less 
value if the vowels are indistinct, lacking in purity or too 
thin, or if they are dominated by the ‘“r” so that the 
song becomes coarse, dull, nasal, hard or dry. The high 
vowel ‘‘i” sung with open beak and a strong air current, 
combined with “r” or, “‘s,”’ results in shrillness. If 
‘sch? is mingled with the “r”’ and “i” the tour will 
be shallow and broad. 
Bell Roll counts among the higher pitched good 
tours, and forms the bridge between Schwirre and 
Hollow Roll.
