"I want students to enjoy the process, and the rest will come. To take students out of their comfort zone, I might ask them to throw the song into a completely different key. Or make them play with only one hand, if they're a piano player, to hear the space in the song. Or ask them to play the whole song up two octaves, or take out all the vibrato, or, for the guitar player, to use an alternate tuning. It's not that the crazy version of a song is the best alternative; it just sends them down a different road so that they come out somewhere fresh on the other side."
