I am somewhat careful about diet and general sense of physical well-being before an important date, as well: that doesn't mean I won't have a beer or a glass of wine, but I'm assured that I won't have explosive diarrhea on stage, so that's one less thing to think about.
That's the ultimate test though. Can you be completely comfortable in front of an audience while there is fecal matter dripping down your leg?
Maybe that's it: if you cannot perform covered in your own feces, what good are you?
P.S. Do you go in the pool with the stairs slowly or do you just jump/dive right in? Maybe it's not exactly the same thing but this might help you better judge your staggering idea and to what extent. How much staggering is enough, etc.
Thanks for your tips. It's pretty horrible to play for other pianists. All the criticisms I have of my own craft gets projected onto them and I think they're all as harsh as I am^^
I prefer people being direct and honest to being "diplomatic" You can usually tell when people are thinking things they are not saying, and all those extra things are of value too. You can be constructive and honest about your opinions without being mean.
There is really only one critique of my playing that I trust or value as at all worthwhile: do they hire me again?
I would personally not want to change or modify my playing to please an audience. That is manipulation.
But, truth is, I wouldn't perform any music I truly despised. I'd imagine most performers are the same way: one has one's favorites, but there's usually some way to make music out of what appears pure drek.
There's an old big band saying: You have to play three tunes for the crowd and one for the band. Keeps both parties happy.
The trick is to pick your audience. I see your point; at the same time our art and missions as musicians IS to communicate with an audience.
