Odington wrote chiefly on scientific subjects, with most of his works existing only in manuscript form. His major treatise, , which
Hugo Riemann says was written before 1300, was first published in complete form in
Edmond de Coussemaker's . In this work, he compiles most of the existing musical theory of his day, as well as some additions of his own. Among Odington's own additions is his theory that, in practice, musicians often favour simple,
just tuning of imperfect consonances, such as the
major third, over the traditionally held
Pythagorean tuning, which was the predominant theoretical framework. For example, he writes: Riemann credits Odington with theoretically establishing the consonance of minor and major thirds before the end of the thirteenth century. Henry Davey, in his
History of English Music, enumerates the following works: • • '''', a treatise on alchemy • • • • • a calendar for Evesham Abbey Elina G. Hamilton, however, has argued that the music theorist and alchemist were two different men, the latter coming from
Eynsham abbey. ==References==
