This German organist and composer is primarily known for his “Fundamentum”. It really is both a theoretical treatise and a compendium of organized vocal music. The idea contends with options for fingering, tablature reading, and reading music. The agreements were written for the intended purpose of familiarizing the audience with approaches for credit scoring body organ and vocal music. Another area of the “Fundamentum” includes many compositions for the cathedral service; especially, introits, a continuous, replies, hymns, mass areas and a Magnificat.
