John W. Ehrlich
Founder and Music Director Emeritus
John W. Ehrlich has been active as a singer and conductor in the Boston and Cambridge areas for more than forty-five years. He is widely admired for his intriguing and adventuresome programming. “From the beginning, it’s been my goal to seek out and perform worthy, important music that is rarely heard,” he says. “As our name suggests, we draw on the whole ‘spectrum’ of master works from the Renaissance to the present day.”
Mr. Ehrlich studied music and conducting while attending the Hartt School of Music, Trinity College, and both Harvard and Boston Universities. His teachers were Robert Shaw, Gregg Smith, G. Wallace Woodworth, Vytautas Marijošius, and Iva Dee Hiatt. Also a singer, Mr. Ehrlich has sung with the Hartford Chamber Choir, Tanglewood Festival Chorus, Cambridge Society for Early Music, John Oliver Chorale, Boston Baroque, and the Emmanuel Church Choir. For eight seasons he was music director of The Master Singers of Worcester.
Mr. Ehrlich retired at the end of the 2023–24 season after leading the group for 44 years.
