These chants are irmoses taken from the Canon to the Theotokos (Ode 1, Ode 3, Ode 9). The chant is performed by the Monastic Choir of St. Elisabeth Convent. The Choir usually uses Znamenny and Byzantine chants, Valamo chant, and adds Byzantine and Greek chants on feasts, alongside Old Bulgarian, Macedonian, and Georgian chants.
