Choral music is a growing section of the musical landscape in Iran and the diaspora that traces its roots to the early twentieth-century when the Tehran Conservatory launched a student choral ensemble. In this document, I trace the roots of vocal music in Persia and document the early history of choral music in Iran, leading up to the 1979 Islamic Revolution, an event that completely halted all performance for a number of years and erasing the momentum choral music built in Iran since the 1950s.For the sake of this document, I am defining “Persian Choral Music” as group singing in more than one part that is being performed or composed either inside or outside of Iran by Iranians, Iranian immigrants, and members of the Iranian diaspora, regardless of style or aesthetic. My research has not examined the entire Persian speaking world, i.e. Afghanistan and Tajikistan are not included in this document. Through this endeavor, I hope to give the artists from this era who were navigating this niche a point of illumination and importance within the greater Iranian musical landscape, showing that this music is not monolithic in scope, style, or aesthetic; Persian Choral Music held, and continues to hold today, a lively diversity, with dedicated performers, composers, and audiences committed to seeing it grow—flowers hidden but still blossoming.
