IMSLP Forums

I'm looking for the original orchestral parts for the aria "Nessun Dorma" from "Turandot" but I did not see the parts on the IMSLP page for Turandot. Does anyone know where I can find this? Maybe I'm missing something really simple because this is a very popular aria.

What instrument is Corni in G? I’m trying to figure out the instrumentation for Beethoven’s 4th Piano Concerto and I do not know if this is supposed to be Basset Horn, French Horn, or something else. Is it a woodwind or brass instrument?
