Look at the musical map of Britain. In Scotland that is in the north of Britain the national instrument is the bagpipe which is the most exciting to the Scots though some people outside Britain think it is tuneless.

The Edinburgh festival is an annual festival of music and drama, it is held every summer.
Welsh romantic and sentimental bards were known even to the ancient world. They still meet every year at the Eisteddfod. And in Wales you can find the best choirs and the best choral music.
