Georgian polyphony
Also called Georgian multipart singing
Living multipart singing of Georgia: drone, contrastive, and parallel traditions by region, used at table, work, and feast. This is a Caucasus seed. It is not Byzantine chant (a later church neighbor, not this folk job) and not a leftover “Europe” bin. Canto a tenore and Paghjella are typological siblings, not children or donors. Church polyphony in Georgia is a later conversation, not a reason to hang this node on Constantinople. Empty extra Received/Given is historically checked. Diaspora choirs are this practice abroad.
