In ゛Canon per Augmentationem゛, the follower imitates the leader with its
figure inverted and augmented twice. Then, what about having the melody
further inverted and augmented quadruply and let it accompany to the
original melody?
What you are listening now is the BGM that I arranged under experiment.

It was initially my rubbish idea, but an unexpected thing was revealed.
The original melody and the quadrupled are partly accorded.
The quadrupled melody starts from the music above and the blue notes in
the upper column are equal to the below.
The accordance happens not only this part but the others.
As seeing at bar 21 above, quarter notes exactly fit to the counterpart, and
the music below shows that the quadrupled melody looks tracing the lower.
Melodic accordance can be seen at the other parts.

I had never dreamed of the consequence like this, even thought this
coincidence was generated from the mutual relation between the theme
and its counter theme.
