COMPOUND TOURS, PARTLY IN ROLLING, 
PARTLY IN BELL-LIKE FORM 
tion of consonants, combined with hollow vowel 
sounds. Frequently the syllables, taken singly, are 
rolling in their nature, but in their sequence they are 
divided off by little pauses or intervals, and therefore are, 
so to speak, bell-like or Schockel-like (rocking, swinging), 
and Gluck-like. To this division belong Knorre (bass), 
Koller, Water Roll, and Gluck Roll. 
| N these tours we get syllables with a large accumula- 
KNORRE (BASS) 
Composition. The best ground tones are o and u; 
the less valuable are e, a, 4. The consonant in evidence 
in this tour is r of a double and treble force (rrr) in con- 
junction with g, k, and n (knorrr, korrr, kurrr, knurrr). 
Bass may run its course in a rolling, continuous form; 
such a tour may be described as Bass Roll. If the 
cohesion is broken (discontinuous), so that the run is 
divided up by tiny beats or intervals, and as it were 
rocking (schockel-like) or gluck-like, then the _per- 
formance is partaking of the bell-like, ringing character. 
Diversions of this nature are known as Gluck Bass, 
Schockel Bass, Koller Bass. 
All varieties of Bass must be sung hollow, with the
