Yes, you can check in anything which fits in the airline specific weight and dimensions as long as the check-in staff is sure that you don't transport any prohibited items and that the package is not to fragile. They might not accept it, when they believe it won't survive the flight.

Yes, but keep in mind that checked baggage travels a considerable distance on automated machinery. The bubble wrap is more likely to snag or tear, especially with an odd sized item such as a music stand. It would be worth your time to break down a card board box and make a makeshift enclosure to go around the bubble wrap for extra protection.
