All of the above, depending on the word which precedes it (Cymraeg)!!!
There is a $10 registration fee for the National Gymanfa Ganu, Burke. It applies to any or all portions of the event.
A little more detail about mutations (the change in initial letter of Welsh words): the word "cymanfa" means an assembly or gathering. "Cymanfa Ganu" means a singing gathering or singing festival. When the word "y", meaning "the" precedes "cymanfa", the "c" changes (mutates) to a "g". Mutation is not much different than slurring words in any language, such as pronouncing "water" as "wadder", except that it has become formalized.
