I don't think it's adequate to train elephants to play music or paint. There are plenty of videos out there that show how brutal the training is as the mahouts "break the spirit" of the elephant into submission. Just my opinion. Not trying to have a go at anyone here. But personally, I would never go to any of these touristy elephant shows. There are Elephant camps around Chiang Mai that allow tourists to interact with elephants and take photos without the elephants having to perform in these silly shows.
