Specifically I just want sheet music with a single melody line that I can then read to play as a 2 part canon on the piano, and later to do as a 3 part where I sing the third.I did this in an aural class at uni. I prefer free but will buy if there's no free options. Catch is I don't want all the parts written out so it becomes an exercise in aural and reading.
That sounds like a wonderful way to stretch the brain in unusual directions. I'd say go to a music store, if possible one with old secondhand stocks, and rummage around. I have a neat little book that presents about 400 canons as single melody lines, but it came from East Germany (in 1988, at the time where there was still an East and a West Germany) so I'm sure it's no longer in print.
That's super, michael! Can you give the title of the book which came from East Germany? (addition: ( because by using a very "narrow" regional-search I only found the books by Rubisch (Leipzig) ( "leichte Kanons und Quodlibets"), 2nd Ed. and "Rundadinella" ( maybe the 1st ed.), and Agnes Hundoegger (Berlin) ("100 Kanons..", which is too few), and G.Wohlgemuth (Leipzig) ("Canons for 2 recorders...").Greetings from Germany, 8_oct!
It's the Rubisch book. It's called "Rundherum", with the subtitle "Leichte Kanons und Quodlibets". I haven't actually counted the canons: I just made a quick estimate by looking at the table of contents.For today's free gift, here are the last three canons. Did you know that Carl Maria von Weber could be so cheeky?
