I depends on your students.A lot of mine just want a taste of music. That's all.I'm wondering what kind of students you have m1469. It sounds like you might be treating them like college music majors -- which is great, but I wonder if they will go for it all. I have scared some of my students when I start talking about "authentic" editions, researching the piece, purity of your interpretations, and all that. I put myself off from playing too sometimes with that.
How about associating a story, or at least a series of emotion-words or physical movements with a piece?
