Moscow Spring A Cappella in Moscow
Moscow Spring A Cappella is an international vocal-music festival and competition staged across open-air stages in the city center, including Revolution Square, Tverskaya Square, and Novy Arbat. Ensembles perform unaccompanied vocal music spanning folk, gospel, blues, and K-pop styles for free public audiences, drawing millions of visitors across its multi-day run each spring.
Unaccompanied group singing is one of the oldest forms of organized music, present in Slavic village choral traditions long before instrumental accompaniment became standard, and it persists today in forms as different as African American gospel, barbershop harmony, and contemporary K-pop vocal arrangements.
