Nat, I have never performed anything note-perfectly in my life.
In different threads on these forums, people have been very kind about examples of my playing they heard via my website. These extracts come from my promo cd, which is a recording of a live recital I gave in Lincoln a few years ago.
My recital, hence my cd, hence my website extracts, are
full of bloopers.
Monumentally huge bloopers. Nobody seems to mind.
The greatest live performances I have sat through have been full of bloopers. I have described them in earlier threads, so will not do so again.
The mistakes we make do not matter. It is what we do about them that counts.
When we perform, our job is not to play all the right notes; this is impossible. Our job is to communicate the music to our audience. The next bit sounds harsh. I promise I do not mean it unkindly. Allowing ourselves to fall apart after a few insignificant wrong notes is childish self-indulgence. Children do this. Adult performers do not allow it to happen.
How do we stop it happening? 2 things, really:
1) Practise and preparation. We cannot expect to play fluently in public anything we cannot do in private. We need such total control over the technical aspects of the music we are playing that mistakes come as a surprise, not as the norm. That's the theory, anyway, but
I have never achieved this, so:
2) We give ourselves permission to make mistakes. We accept that technical perfection can only be achieved with editing in the recording studios. We accept that: a) most people cannot tell, and therefore do not care, when we hit wrong notes

b ) those that
can tell sympathise; c) the least significant mistake we can make is to hit a wrong note
Here is Steve's descending order of performers' musical crimes:
3) Unmusical playing - unbearable.
2) Rhythm mistakes - alter the character of the music to an unacceptable degree.
1) Wrong notes - so join the rest of the human race.
Hope this helps.
Steve
