參考: my opinion
Music is very personal and subjective matter. No one is ever correct and no one is even wrong (well too wrong anyways). In a petition there are many factors the judges should and will consider
mainly if the player has truely understood the STYLE of the piece of music (eg. when playing Bach
can this person really play the style Bach intended or is he/she just playing in their own style that doesn't suit the music?). Some judges are musicologists
meaning they are extremely picky about the different styles
eg. Bach style
Mozart style
Phillip Glass style etc e Then es expression - this can be quite experimental by the player
as long he/she keeps the style correct. Expression is not just emotional expression but also pharsing - ie. treating the piece of music like a conversation
where you have mas and full stops. This is what gives the emotional feel to the music. So Pharsing and emotions go hand-in-hand. Speed - well of coz one should play close to the speed that the music asked for. Never too fast - if it's too fast
then it isn't possible to hear the expressions and pharsing. If it's too slow
then it's boring! The player should make use of speed when performing and this is probably the hardest because one will no doubt be nervous on stage
you will speed up even if you don't want to! I'm only speaking from an amature player's point of view. Any professional musici here are wele to correct me.
