better pianist, worse pianist.. compared to what ?

[okoie]

Hi friends,
Which are the parameters by which we can judge a pianist's  rendition ?
Are there actual, objective values to employ and if,which are?
The only objective things I see are speed and overall precision
Am I wrong, miss something obvious to all except to me?

In my opinion, Maybe each individual has their own parameters. But one ultimate goal : To make music.

For me, the musicality is all that matters, precision and speed is a bonus since you're going to be practicing a piece over and over.

If it's your own music you're having problems evaluating, try Camera recording your own playing.
