No one's ever said, "Hey, you know what Skyrim really needs? Musical bears!"
But the fact that no one ever asked for it didn't stop one modder from adding musical bears into the game through a mod appropriately named "Bear Musician." The mod was put together by a Russian modder who goes by rsv_rsv on the Steam Workshop.
The Bear Musician mod adds a bear which plays the guitar version of Misirlou by Dick Dale, made popular by the Quentin Tarantino film Pulp Fiction. It's the catchy guitar track that Uma Thurman and John Travolta dance to before she overdoses and needs to be resuscitated in a couple of scenes later. The track was also previously used in the Rayman Raving Rabbids games' dance minigames.
Once you've followed the instructions on the Steam Workshop and installed the mod, you'll have a spell called "Bear with Lute" that you can cast at any place to summon the Bear Musician, who will play the lute for as long as you like until you cast the spell again to unsummon him.
Keep in mind that the bear is completely tame, and will not attack townsfolk, so feel free to cast him in the middle of Whiterun.
