Tune Smithy does this
Here is an example - it's generally regarded as musical.
You hear the tuning first. Then you hear a seed phrase. Everything else you hear is generated from that tuning and the seed phrase, and incorporates all the notes of a strict sloth canon in many parts.

Playlist of them all: Fractally Generated Tunes - 'Intricate as Snowflakes'
The similarity is that if you play the tune faster, and leave out some of the notes, the result is the same tune again. You can assign different instruments to each of those slower versions of the tune and the result is a strict sloth canon - though sometimes the canon is transformed in various ways. This construction is similar to that used for the Koch snowflake fractal.

It is interesting that this method creates satisfying music, even though the method of construction is so different from conventional composition. Maybe it is to do with the way many natural sounds have some features of fractals - and composed music also has many of the features of fractals too.
