A goatsinger has a sense of the tragedy and so looks for the jokes.
A goatsinger will sing.
A goatsinger will tell stories, recite poems, perform any part required.
A goatsinger will play his/her instrument as best he/she can.
Essentially, a mix of music and some performance --
maybe storytelling, maybe puppetry, maybe mime --
always a touch of the theatrical --
with the simple understanding that story and music
belong together.
