Another perpetual canon.

This one has two notes in the dux before the repeat signs. That requires an expansion of the technique that I discussed a few days ago: simply that a double counterpoint needs to be calculated for each note that occurs at the critical juncture of the repeat.

In other words, I needed to calculate D.C. for each of those two notes. If there were three, I'd have to do it for all three etc.

I also needed to be certain that the number of measures inside the repeat signs was a multiple of the number of measure that the dux had before the repeat --this ensures that everything works out evenly on the repeat.
