A Cymanfa Ganu[1] (Welsh pronunciation: [kəˈmanva ˈɡanɨ], Singing Festival), is a Welsh festival of sacred hymns, sung with four part harmony by a congregation, usually under the direction of a choral director.
In Wales, a Cymanfa Ganu is still an annual event in some chapels and may take place at festivals such as the National Eisteddfod of Wales and the Pontardawe Festival. Cymanfa Ganus are also occurring round the world - wherever people of Welsh heritage live.
The Cymanfa Ganu is one of the unique features of Welsh culture and its preservation is being supported by a number of Welsh cultural associations, such as the New Zealand National Gymanfa Ganu Association and the Welsh National Gymanfa Ganu Association (North America).
Once a year, a four day North American Festival of Wales (a Gymanfa Ganu, commonly just referred to as a National) is held in North America over the Labor Day weekend. The four day festival opens on Thursday night with a Noson Lawen, which some call a Welsh Amateur Night. The weekend continues with an evening banquet on Friday and a Saturday concert, generally featuring a Welsh male voice choir and soloists, both from Wales.
Sunday is the defining day of the four day festival which begins with a bilingual church and memorial service. After a brief intermission, this service is followed by afternoon and evening sessions of the Gymanfa Ganu itself. A unique feature of the gymanfa ganu is the seating separation of alto, soprano, tenor, and bass singers into sections for the four part harmony singing. And while the Gymanfa Ganu is conducted with the dignity of a church service, it is not unknown for the musical conductor to stop the singing when one or more of the voice sections wanders from the desired harmony and needs special attention.
Interspersed between the formal proceedings are frequent sessions of spontaneous singing of favorite hymns. A Welsh Marketplace, offering Welsh products, artifacts, souvenirs, recordings, and books, is also available during the days of the festival.
The Welsh National Gymanfa Ganu Association is the main organizational body responsible for putting on the event.
