Accuracy when performing pieces. help!

[rovis77]

Hi, when you perform your pieces how much accuracy do you have?. I sometimes fin I can play my pieces with great accuracy and other days Im not as accurate. Is this normal??

Perfectly normal.  You are not a machine!

That said, you might find it helpful to think a little about what circumstances you play better in, and what circumstances worse.  You might find some common threads regarding warmup, or time of day, or number of cups of coffee, or current relationships with your significant other, or... who knows.  You might not, too.

When I was 14-16, with adequate practice to eliminate nervousness, I was extremely accurate.
Now in my sixties, it takes more practice to stay current and some days are quite bad to start with.  Muscle response is much less predictable in your sixties.  Those rubber bands we call muscles are much more temperature and use sensitive when you're aged.  Just sleeping 6 hours makes everything stiffen up and it now requires half an hour after awaking just to walk around confidently.   
I didn't have time to  play much in the forties and fifties, I'll leave opinions there to others.
