The Way of Eiheiji: Zen-Buddhist Ceremony

Shōmyō (声明) is a form of Japanese Buddhist chant practiced primarily in the Tendai and Shingon traditions. It is an a cappella, liturgical vocal music used to intone sutras, dhāraṇī, hymns, and ritual formulae in temples. Two main stylistic groupings are recognized: - Ryokyoku (呂曲): the more elaborate, melismatic, and technically demanding style. - Rikkyoku (律曲): the simpler, more syllabic, and easier-to-memorize style. Textures are predominantly unison (male monastic voices), with free, breath-governed rhythm and subtle microtonal inflection. Although primarily unaccompanied, wooden blocks (mokugyō), bowl gongs (keisu), or hand-clapping may mark ritual timing in certain services. Texts appear in Sino-Japanese (kanbun) and in Sanskrit (Siddhaṃ/seed syllables) as transmitted through Buddhist liturgy.

Buddhist music is the broad family of liturgical chant and ritual sound practices associated with Buddhist traditions across Asia. It centers on the vocal recitation of sutras, mantras, and dhāraṇīs, often performed a cappella by monastics or lay chanters, and is designed to aid concentration, devotion, and the transmission of teachings. While primarily vocal and modal, instrumentation appears in many regional practices: Tibetan rituals feature low multiphonic chant with drums, large cymbals, horns, and shawms; Chinese fanbai and Korean beompae retain courtly timbres; Japanese shōmyō emphasizes refined, unison vocal lines; and Theravāda communities in Southeast Asia maintain austere Pāli chant with minimal or no accompaniment. Common traits include restricted melodic ambitus, formulaic melodic contours, free or flexible rhythm, and text-forward delivery in sacred languages such as Pāli, Sanskrit, Tibetan, Chinese, Korean, and Japanese.
