The canon is contrapuntal compositional technique, which sounds more complicated than it really is. When you go through known canons, you will find it easy. Somebody starts singing, other joins later and sings the same melody. Altogether It sounds beautiful. I arranged ten world songs and two classical compositions for DADGAD guitar tuning. Where the canons had opportunity to start at multiple sies, I made more versions. Lots of beautiful moments, when you play on DADGAD guitar. Songs: Viva la musica; Dona Nobis Pacem; London's burning; Frere Jacques; Vent Frais; Row, Row, Row Your Boat; Ah, Poor Bird; Hinei Mah Tov; Merrily, Merrily; Kaeru No Uta; Vyletela holubicka.
