Is it bad to listen to a recording of a piece you're going to play before reading it for the first time?
Yes. Why?
I ask because I think that if I got used to that with time maybe I'd be dependent on that ç, and couldn't play a piece by myself without listening to a recording first
It's bad, because you will imitate all of the faults of the recording when you don't know what the composer really has written at this moment. And the tempo is always too fast in almost any recording.
I like to listen to piano pieces before I play them myself, because it gives me an idea of what the piece is about. Just a general idea... I find it very hard to work out everything for myself all alone, and it saves me a huge amount of time when I just listen to it for a few times to catch the melody and rhythm. Of course I don't listen to any badly played youtube-videos, I rather try to find something that I really think is extremely well played.But I do think as well that it would bring me further in playing if I did everything by myself.
