Stephan Mahu (also Étienne Mahu, * between 1480 and 1490 in the then County of Flanders; † 1541 or later) was a Franco-Flemish composer, singer, trombonist and bandmaster of the Renaissance.
There is no reliable information on Stephan Mahu's origins to date; Mahu was perhaps a member of the court of Queen Anne of Bohemia and Hungary (1503-1547 who was the wife of Ferdinand I. He was as a singer and trombonist in the court from the early 1520s. From November 14, 1528 onwards he was contractually bound to lifelong service with her and Ferdinand. In addition, between September 1529 and March 1532, he took over the position of vice-kapellmeister of the Vienna Hofmusikkapelle of Archduke Ferdinand under Arnold von Bruck until 1539. His name appears for the last time in 1541 as a trombonist in this chapel. The place and date of his death have not been recorded. (Source: Wikipedia)
