CHAPTER XIII 
SIMPLE, CONTINUOUS TOURS IN ROLLING 
FORM 
HE characteristic of all rolling tours lies in the 
“> unbroken continuity of the syllables in conjunc- 
tion with the consonant ‘“‘r.”’ In all tours with 
a rolling rhythm, the r is audible, in one more distinctly, 
in another less so. 
A roll without an r is a contradiction; the syllables 
are formed in the most intimate blending with this 
consonant, which thus imparts to them the rolling 
movement. If the r is absent, there can be no unbroken 
roll, no continuous turning, whirring, sound as the song 
progresses. 
The simplest Roll tours are found on the higher 
scale, and start with Schwirre as the highest. Then, 
somewhat lower in pitch, comes Bell Roll, and lower 
still (medium down to the deepest) comes Hollow Roll. 
SCHWIRRE (THE WHIRRING, WHIZZING TOUR) 
In the composition of Schwirre the ground tone is 
1,” blended with “r,’’ and sometimes also “b,” and 
ce 9

continuous fashion. 
Its quality depends upon the purity, clearness of the
