Does anyone know where I can find these etudes? It seems like I've looked everywhere, but with no luck. Is it possible that they aren't even published yet?

I wrote to his publisher about purchasing the sheet music for the Philip Glass Etudes for Piano and received this reply on April 28, 2008:

"Thank you very much for your enquiry. These Etudes are not yet complete. Philip Glass has written 16 of a projected 20 Etudes and they are consequently unavailable to purchase. Philip Glass maintains performance exclusivity on these pieces too. Sorry I cannot be of further assistance."

Well, they are apparetnly recorded.
There are some people who are very good at listening to recorded music and transcribing the music onto paper.

I am not a big fan of breaking copywritght laws, but when things are not published, or when you have to purchase an entire score for one part I don't think God would object too much - - if you are doing it for yourself and not making money from it.

Thanks to both of you: I have recently found out that they are as of yet not entirely complete, and I do not have the ear, patience, or desire to write out the etudes by hand from a recording! Thanks to both for your help, it is very much appreciated. I will just wait until they are completed, and maybe then will I be able to find a book of Glass's etudes on music store shelves!
