Cantus

A cantus (Latin for 'singing', derived from 'cantare'), is an activity organised by Belgian, Dutch, French, Baltic and Afrikaans student organisations and fraternities. A cantus mainly involves singing traditional songs and drinking beer. It is governed by strict traditional rules. The use of this dates back a few centuries and was inspired by German student organisations; however some of the songs that are sung date back to the Middle Ages. Cantus probably shares same roots with Commercium, Sitsit and Tableround.
