Apdziedāšanās (Ritual Song Dueling) or apdzīduošona is a traditional singing practice where two or more groups of singers compete in a mutual singing dialogue. They take turns singing satirical, witty, mocking, playful, or challenging quatrains.
Intangible cultural heritage (ICH) is a source of cultural affiliation, identity and self-awareness. It includes forms of customs, games and oral expression, knowledge and skills, and related instruments, objects, artifacts and cultural spaces, which are recognised by the communities, groups and, in some cases, individual, as part of their cultural heritage.
