This week the choir sings two anthems, the first “Rejoice, Rejoice, the Savior Comes,” by William Tans’ur and arranged by Michael Burkhardt. Tans’ur was an eighteenth-century music teacher, bookseller, and composer in rural England. Born Tanzer, as an adult he changed the spelling of his surname and styled himself a “musico theorico.” His music has a forthright and somewhat unrefined character typical of rural English music of the time. The second anthem is “Mary’s Magnificat,” by the modern English composer Andrew Carter. The piece features a soprano solo, sung this week by Ellie Weikle, a Westminster member currently studying music at James Madison University, as well as a violin solo by Leah Patek, a junior at CHS.
