Well your opening sentence was: A simple question; if you were recording music for your students.
So that is what I went off and indeed most students won't really explore music in this fashion from my experience, if they do they already would have music lists of their desired works.
Completely understandable given how I phrased the question. I was primarily thinking of my own students but I thought, as long as I'm going to the trouble of recording all this music I may as well make it available for others. I was just trying to avoid writing a long winded question that nobody could be bothered to read so I (perhaps mistakenly) left out many details.
Whether or not this is a worthwhile pursuit seems to be what you are responding and it is a question worth considering. Personally, I have always appreciated being able to listen to recordings of sheet music anthologies so I figure there must be others out there.
In any case, whether or not I should do this wasn't really the question I was asking. What I'm really interested in is people's view on genuine but imperfect performances vs. artificially polished performances. Do you have any views on that? I'd love to hear them.
It's not a crutch it's a way to listen and watch the music.
Agreed, they definitely don't have to be but I have seen them used that way by some of my former students. And everyone has their own preferences. Personally, I find looking at the score while listening to music far more interesting and entertaining then midi visualisers. Each to their own, I guess.
