Great videos, I've quite enjoyed them, thank you. I have to take tiny issue with your comments ending around 1:45- I would agree it's not of "much" use for "real world composition" in the sense of building some sort of dramatic musical architecture, but... for one, I recall playing the "table canon" by Mozart as a boy and I think it certainly to some extent can come across as a kind of parlor trick. But it does have a certain theatrical flair that a talented show person could capitalize on. And on a more "serious" note of musical accomplishment, I would argue that the music of Webern (and the other serialists, for that matter, but W in particular) is imbedded w/EXTREMELY inaudible (in concert hall on first listening, esp) but highly "useful in real world composition" canon elements. All that being said, it's a tiny disagreement. In the context of your series I understand what you were getting at and agree with your point.
I have composed a canon in Bb using mostly imitation and I noticed that because I was writing for a woodwind quartet, I had to have different instruments reach different dynamics at different times, otherwise the flute and bassoon would be drowned out by the oboe and clarinet, especially when the flute reaches its low register. I had it at every 2 bars(length of phrase in the canon is also 2 bars). The bassoon was playing a bass line separate from the melodic lines but also I noticed the harmony changing as the canon progressed. At first it was a Bb major chord every other beat. But then it changed to there being a G minor chord(or D minor, can't remember, but I know it was different but closely related to Bb major). But the first and last beat with a tonic chord stayed that way. I was wondering, is this harmony change okay in a canon as long as it changes to another closely related chord?
You really have to consider the instruments' registers and ranges when writing any kind of counterpoint, not just canon. Counterpoint does not make balance problems OK, unfortunately.
I may not be the most qualified to answer this (I'm a self-taught amateur), but my totally uninformed opinion is that it's fine. Gm and Dm (especially Gm) sound quite natural following Bb. The progression from Bb to Dm is interesting, too, as it contains the same tones, but with a half-step drop from Bb to A. Is there a recording of it online? You've piqued my curiosity.
