Vitali: Artificii Musicali, Op.13

There are 40 canons included here from Giovanni Battista Vitali (1632–1692), and interspersed among them there are four that can be classified as riddle-canons or enigma-canons. These intriguing pieces are accompanied by a brief Latin motto containing the key for their realization, which is left to the reader to decipher. (Brilliant Classics)
