This is the performed end of the Buddhist corpus — not scripture to be studied but words to be said aloud. The catalogue files all 97 witnesses as Chanting, and the titles lay out the northern liturgical repertoire.
At its centre is the suat mon (sut mon), the chanted suttas and paritta: the much-loved Mahāsamaya Sutta (Sap mahasamainya), the namo/buddhaguṇa invocations (Tika namo, Putthakun luang), the fifteen-day cycles of recitation. Around it runs the distinctively northern thon — occasional recitations for the crises of life, and above all for death: thon for the newly dead (thon tai, thon phi tai), thon for the house and home (thon ban, thon huean), thon to dispel the inauspicious (sut thon sappakhuet). And at the edges sit the su khwan soul-callings (su khwan for a person, even for an elephant) and the ariradhana invitations to preach — the Kam alathana tham wetsantala, the summons to recite the Vessantara at the Thet Mahachat.
This is the genre where canonical Buddhism and efficacious saiyasat are the same performance seen from two sides. A sut thon sappakhuet — a recitation to drive off the inauspicious — a rite against kalakini (bad-luck), a volume that binds sut mon directly to holasat (astrology): these are protective chanting as efficacious action. The companion article on Magic & Ritual describes the benedictory, consecratory end of saiyasat; this genre is that end, filed under "Chanting" because the technology is a spoken formula and the setting is the temple. For this archive's esoteric priorities, the liturgy is not a backwater — it is where the protective and apotropaic core lives in its most public, communal form.
Written overwhelmingly in Tham Lanna (94%), with a notable 15% monolingual Pali — the chants themselves are Pali, so a share of the corpus needs no vernacular at all. Its support leans more to paper (29%) than the scholastic genres do, exactly as one would expect of a text opened and read during performance rather than shelved. It is spread evenly across the upper north (Phrae, Lampang and Nan almost level) and reaches back further than most — a witness dated to 1541, the 16th century.
