Audrey Ekdahl Davidson was a professor of music for many years at Western Michigan University. In honor of her retirement and her history with the Society for Old Music, an organization that she founded in 1966, this collection of music has been selected and prepared. The transcriptions were all designed for performances by the Society for Old Music, and were used in concerts for the local community, the International Congress on Medieval Studies, and other audiences in Michigan. The Society's concerts ranged from medieval chant and monophonic song to polyphonic choral works, and each concert focused on a particular topic, perhaps most successfully when music-drama was joined to liturgical display. The collection is a fitting tribute to tireless scholar, and an asset to any student of early music performance.
