Attribution Levels

To reflect the many degrees of uncertainty surrounding works attributed to Josquin, we have divided the repertory into six categories. For other composers, with respect to whom the state of the evidence is generally less variable, we use only four levels: 1/2, 3, 4/5, and 6.

Level Marker
(Josquin)		 Marker
(other)		 Meaning Notes
1 ✓ none Secure As good as we can do given the available evidence
2 (✓) none Slightly less secure
3 (?) (?) Tricky Better than even odds
4 ? ? Questionable Less than even odds
5 ?? ? Doubtful
6 ??? ?? Very doubtful Overwhelmingly attributed to another composer

For a work attributed to two composers, the respective attribution levels are typically 1/6, 2/5, or 3/4, though 3/3 and 4/4 are also possible.

Rough quantitative mapping of attribution levels:
