The program is taken from the Squarcialupi Codex, a lavish manuscript of 14th-century Italian music, named after a 15th-century organist at the cathedral of Florence who came into possession of it. It is located in a Florence library but is now available in a very expensive facsimile. The music, all secular works originating in Florence, is grouped by composer (a portrait illuminates each group) and arranged in chronological order of their age. The first five composers have only six selections here, with the rest of the disc devoted to Bartolino and Andreas. The disc takes its title from Giovanni’s madrigal in praise of music, the first piece on the disc.
