Answer:
The harper went inside and talked to Hrothgar, and then played his harp and sang of old kings’ glorious deeds. Men became quiet, and Grendel says that the very landscape hushed “as if brought low by language.” The harp-player, known as the Shaper, offered to sing of Hrothgar’s glory for pay. The Shaper’s music is extremely powerful.
