To be honest, I sometimes wonder if Beethoven were alive, how would he have played it? Unlike Grieg whose performance of the Wedding was recorded and therefore I noted that he played it in roughly two minutes, other pianists in fact played it in around 3 to 4 minutes.
I decided to spend the day listening and viewing youtube performances of different concert pianists play different pieces. I heard a version of the first movement of Moonlight Sonata played by Glenn Gould which was unusually faster than how I heard other pianists like Cliburn play it in the past, and I was surprised that no one was critical. On the other hand, I also listened to Prelude from Suite bergamasque played by Claude Arrau and he was slower than Aldo Ciccolini (did I get his name right?) and it also sounded just as wonderful. I guess I do now see the wisdom of how one makes a piece truly an inspiring melody and an artful masterpiece as compared to others who played it as if they were joining the music olympics.
Two weeks ago, I attended a master class held by one of Malaysia's foremost pianists, Claudia Yang. She handled 5 students and I found her comment interesting. One played a Prokokiev piece and she was playing some sections too fast. She said that what was more important is that we hear the notes distinctly and clear, not as if they were a blur because we were playing too fast, and she commented that "quite a lot of musicians today are more after playing for speed rather than for clarity and from the heart, or from expression.". Then, there was a girl who played Lizst Hungarian Rhapsody No. 11 , and although the girl actually had very good technique, Yang emphasized the importance of letting the audience feel the "ambiance and atmosphere" which Lizst wanted to depict in the notes which was festive, and dancing, not like a march.
I also realize that it would really help to also do research, at least find out what the composer was going through when they wrote the music. Thank God for the internet and abundance of documentaries!
