Motion
from/to an inner voice, Untergreifen. This describes a
linear progression at a higher
level that connects a note of the Urlinie
with a note of an inner voice at a deeper level. An initial
ascent is an example of motion from an inner voice at a deep level.
In mm. 1-4 of the aria, the ascending fifth  -F
is a motion from the inner voice ()
to the Kopfton of the Urlinie.
Mm. 5-6 exhibit another motion from the inner voice, from C to  ,
of the Urlinie. Such motions serve to prolong
the deeper levels. The example below illustrates both types of motion as they serve to prolong the
of the upper voice in Variation 16. Motion to an inner voice occurs
in mm. 14-19 of the fugue, where a third
progression, F--D,
prolongs the underlying harmony, I,
by moving from the upper voice, F, to the inner voice, D. |
