#byzantine chant

• Anastasimatarion variant — An archaic form or niche regional variant for 'anastasimatar'; a liturgical book used in Orthodox churches of the Byzantine rite containing the Sunday chants dedicated to the Resurrection of Christ, systematically arranged according to the eight church tones. Preserved in old manuscript inventories or mentioned in past monastic parlance, this form structurally emphasizes the direct etymological link with the feast of the Resurrection.
• Anastasimatarion — An official liturgical book used in the Orthodox Church comprising the chants appointed for Saturday evening (Vespers) and Sunday morning (Matins) services, focused exclusively on the theme of the Resurrection of Christ and structured based on the eight tones of psaltic music. This structural work is indispensable at the cantor's stand, gathering hymns such as Dogmatika, Resurrectional Stichera, and Apolytikia from the Octoechos.
• Anthologion — A liturgical book specific to the Eastern Orthodox Christian ritual of Byzantine tradition, containing a structural selection of the most important chants, prayers, troparia, and readings extracted from the Menaion, Octoechos, and Triodion. This ecclesiastical compendium was created for practical needs to centralize Sunday services and major feast days into a single volume accessible to priests and chanters.
• Apehema — A graphic and phonetic variant of the term 'apechema'; a short melodic formula performed by the cantor before starting a church hymn to indicate the modal structure and pitch of the mode. This simplified form often appears in church music textbooks printed in the early 20th century.
