Teiler. A note that divides a large interval into two
roughly equal portions, usually in a bass progression. The dominant
(or subdominant) can act as a divider of the tonic and its octave,
and usually forms the root of a contrapuntal chord. The third can
act as a divider of the fifth. The term divider is especially useful
in distinguishing functional harmonies (Stufen)
from contrapuntal harmonies. A leaping passing-tone (springender
Durchgang) fills a similar function in the upper voice.
The example, from Variation 14, shows III
as a divider between I
and V in the
first half of the variation.
