"Play what you mean, and mean what you play"
Surely it's play what they meaning (meaning the composers) and mean what you play?
Only if that's what you intend/mean to play.
Then the thoughts of the great and good don't matter?
But, if you don't care about expressing that, if it's not what you intend to express, if you don't take the time and effort to study those things and explore and such, THEN they don't matter.
Confused. Are you saying there is something beyond Mozart's thoughts in music? That you can get there without going through Mozart's thought?
Ah, monsieur. Does it matter to you what I think regarding that?
Does what gets posted in a forum matter?
Matter ...in the long run.
