Solution
to Canon
6. Fuga canonica in Epidiapente
How
many voices are there?
A
C-clef and a G-clef indicate that two canonical voices play the Royal theme,
together with a third counterpoint voice in the lower section.
Is
there a
%
? Look hard.
You
will find the %
at the beginning of measure 11.
What
are the transformation principles?
Look
at the title.
\93Fuga
canonica in Epidiapente\94 means a canonical fugue at the fifth.
The
C-clef and G-clef on the same
line indicate that the leader starts on middle \93c,\94 and the follower
starts a fifth higher on \93g.\94
There
are two transformation principles:
1.
Time
displacement, by a whole ten measures.
2.
Space
displacement, a fifth higher.
In addition, this canon is actually written as a complete fugue, with contrapuntal development, and modulation of the Royal theme to different keys.
Geometrical
projection:
Starting
from two superimposed like triangles, or other forms, perform the two
transformations.
The
result would look like this:
Performance:
Here
is a recording of the leader played by the flute, and the follower by one hand
on the piano. Perform all three voices by playing the lower counterpoint line
on the piano.
