Using the same basic technique as yesterday, I wrote today's canon. It was fast and dirty but reasonably successful. If I had more time, I'd edit details and make the melodies more effective.

First, I made up a harmonic progression of the type suggested by C.P.E. Bach in his Essay on the True Art of Playing Keyboard Instruments as a way of improvising preludes. Obviously, writing a canon is different than improvising but the type of harmonic progression is often the same.

Since the canon follows at a sixteenth note distance, the last 16th of each measure in the dux is the common tone. The only case in which there is no common tone is measure 20 where the last note of the dux is a non-harmonic anticipation. In the next measure the same pitch is the first note of the comes and is a chord tone.
