As I start to truly master a piece, I find that I go through a phase of not listening to CDs of it at all. I naturally loose interest in other’s playing as I get more and more interested on my own.
However, I often go back to CDs at certain intervals, and I am often surprised that I had not noticed certain details before.
So, at first (during score work and work away from the piano) I tend to listen a lot to CDs. My main aim at this point is simply to get the sound ingrained. That is what the music sounds like, and how different performances bring/fail to bring the music alive. At very first my listening is mostly uncritical – I just want to get acquainted with the piece. With repetitive comparative listening, criticism comes naturally into it and I start to develop likes and dislikes and predilections for a interpreter(s) over others.
As I start working at the piano, I tend to listen less and less to CDs and at some stage not at all. This is not planned – it just happens.
As the piece comes together, I find that I start listening again to CDs – but at much wider intervals than in the beginning – to check things out so to speak. At this point, having actually experienced the piece, I find that the quality of my listening improves tenfold.
Sometimes I get quite sick of the piece (from so much listening) – how fast you can get sick of listening to a piece is a sure measure of the inferiority of a composition. If this happens, than it is a very good idea to drop listening to it for a while so that it can regain its freshness (if it doesn’t than that’s definitely an inferior composition). Alternatively, there are pieces that I first hear and seemingly cannot get enough of it. These are the pieces that go in my future repertory list.
In my experience, it is far easier to get sick of listening to a piece than it is of playing a piece. I guess this shows how passive listening is an inferior way to truly appreciate music.
It is only in the last 15-20 years that a truly formidable repertory has become available on CD, so I doubt not listening to CDs has too much of a negative effect – the great majority of pianists and composers from past times did well without CDs.
I also think that for an advanced pianist with good sight-reading skills, listening to CDs may not be necessary at all.
It is for intermediate and beginners that CD listening can make a huge difference, and cut learning time dramatically.
Best wishes,
