Early music and dance enthusiasts will be familiar with the work of authors such as John Playford, who published the series of dance instruction books called The (English) Dancing Master from 1651 onwards, and with Jehan Tabourot, who in 1588 wrote instructions for the dances of his youth under the anagrammatic pen name, Thoinot Arbeau, published in France as Orchésographie in 1589. There is evidence of earlier dancing masters – dance instructors – from the medieval period, but the first to write surviving choreography were in the renaissance of 15th century Italy, and the earliest of these was Domenico da Piacenza (c. 1390/1400–1476/7). This article briefly outlines Domenico’s dance manual of c. 1450, the social context of his dances, his wide influence, and some ways in which his choreography and music notation can be interpreted using one example, La giloxia (The jealousy), a video of which begins this article.
