The musical appendix of Vienna, Österreichische Nationalbibliothek Cod. 5094 contains ten polyphonic pieces and twenty plainsongs, written by twelve different hands in six different types of notation, including letter notation and early German organ tablature. It is not, however, a random collection of disiecta membra, rather an anthology (florilegium) for the use of organists, collected c.1443 by an Austin friar from Munich visiting Vienna, who owned the parent codex.
