78 THE ROLLER (CANARY 
Bell Roll. The consonants are 1, h, d; the syllables 
formed by combination, therefore, are lilili-hihihi— 
dididi. 
The quality depends upon the fullness and purity of 
the vowel sound, the force of the consonants, 1, h, d, and 
the measure of the pauses. These pauses regulate the 
tempo, the beat, in other words the rate at which the 
syllables are repeated. 
THE HAMMERING BELL 
Lilili gives the best effect, if not too slow, and the 
effect is also good with hihihi if the beat be not too slow, 
otherwise the tour is jerky. Dididi is only good when 
the “‘d” is feeble, and the “i” pure and soft; the beat 
should be fast. If the vowel is hard and the consonant 
is strongly marked, the tour has a knocking effect, and 
may be called Hammering Bell. 
As its name implies, a good Bell tour reminds one 
of the sound and the beat of a little tinkling silver bell. 
The simpler the sound, the more beautiful is the effect. 
The tour loses value if the vowel “i” is not pure or 
borders on “e.” 
Bell is faulty if any but the above-named consonants 
come in; “s,” combined with ‘“d” (dsidsidsi or 
dsedsedse) is very dangerous; these noisy, unmusical and, 
therefore, ugly combinations, stifle the ground tone, 
and this series of syllables leads to Schnetter 
(dschedschedsche). 
Bell is sharp when the “i” is very thin and very 
high, with “d” or “h” (perhaps a trace of “s”’) sung 
in sharply divided syllables. 
Nasal Bell is a melancholy tour on i, e, or a, com-
