東大寺 お水取りの聲明 (Buddhist Chant of Shuni-e Ceremony, Todaiji)

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.
