Musical structures can be used to give image a place in time and sound can change the image. Sound doesn't presents an image by nature, on the contrary; sound is in its core just sound, nothing more, nothing less, like the image.
The question how they relate to each other is the main theme of the chronicle as a whole.

Can you listen fresh and clean to the slow part of Mahlers 5^th symphony after seeing "Death in venice"?

Every part of the chonicle has been an investigation in the relation between sound and image;

part 1, "passacaglia", is about variation.
part 2, "nachtmusik", transparency in sound and image.
part 3, "nachtmusik 6", cinema/tv music and image.
part 4, "the handmirror", story telling
part 5, "canon", time/sound-based composition.

Canon has five parts, the first, third and last part make use of small videopieces. Part two and four are build out of collages.
Every part has its own soundtrack, part 2 and 4 have 8 soundlayers which are created every time on the fly.
In the Canon sound is the basis of all parts and trickers the images.
Canon is build with the use of Macromedia's Director.
