Turn It Up to 11

By turning the volume knob to 11, you can play a shredding riff or solo on your lute or lyre to rupture the eardrums of any creatures within 30 feet of you. Said creatures must succeed on a Constitution save equal to your spell save DC or take 5d8 thunder damage and be deafened for 1 minute. On a success, they take half as much damage and start headbanging (headbanging has no effect). Any glass within the area shatters. 

You can cast this spell using a higher spell slot. Add 1d8 thunder damage for every spell slot above 3rd.
