(b Immecke, nr Meinerzhagen, 1536; d Dortmund, Aug 6, 1609). German theorist, teacher and Kantor. He was educated first in Münster and Dortmund, and later at Cologne University where he received the MA in 1560. After serving as teacher, Kantor and administrator for several years in various schools, mainly in Dortmund, he took up a post in 1567 as Kantor at the famous Reinoldi School there; he became Rektor in 1582 in succession to his former teacher and long-standing friend and colleague, Johann Lambach. His work in this post was widely acclaimed and in 1587 he was made Comes Palatinus by Emperor Rudolf II.
He is important for his treatise Erotematum musicae, originally published in 1573 under the title Musicae erotematum, and subsequently reprinted three times. The treatise, of the musica practica type, presents the fundamentals of music in question and answer form. For his formulations Beurhaus borrowed considerably, as was customary in a treatise of this kind, from other German theorists of the time, notably Agricola, Faber (both Gregor and Heinrich), Figulus, Galliculus, Ornithoparchus, Wilfflingseder and Zanger....
