Bagpipes of Invisiblity

These magical, ornate, 7-pound dark wood bagpipes blast loud and obnoxious music, and while the pipes are playing, the performer is invisible from sight. The player cannot cast spells, or take the Attack Action while playing this object. The performer and all within 60 ft also have disadvantage on sound-based perception checks. The player automatically fails all sound-based stealth checks,  and an attacker must succeed on a DC 10 perception check to make an attack, yet all attacks are still at disadvantage due to the performer invisiblity. All concentration checks within 60ft are at disadvantage unless the creature is deaf. 

Notes: Disadvantage: Stealth, A creature must spend 1 hour practicing to blow into the Hide Bag
