Original method of telling beowulf?

scop

Explanation:

A scop (pronounced "shop") is a storyteller or traveling minstrel. A scop memorized poems and stories and recited them in front of audiences. The poems and stories changed as they were passed from one scop to another, like a game of telephone. Beowulf was probably first told by scops.

I think it was either tapestry or just telling the story out loud
