I've been using recording recently for a very specific purpose. I'm playing a number of tunes at my sister's wedding this Saturday. I already know that some things I do sound find in my ears when I'm playing, but, when I hear them on a recording, I realize they're less than ideal. So I've been recording a tune, listening for what works and what doesn't, then going back and trying it again with a different idea. It's made a big difference to me. It's not as useful as having a knowledgeable player make suggestions, but it's the next best thing. Like I said, some things, I just can't hear what they sound like to a listener.
Having said that, my theory is that the people who hear the most of what's going on in a tune are other musicians. The general audience, especially people who aren't familiar with Irish music (in my instance- I forgot, not everyone here plays Irish music
) are very forgiving and don't hear much of what's happening good or bad. If you get a decent ryhthm going, that will carry the day.
Side note on this wedding: my sister is a bit flambuoyent (spelling?) and her friends are a bit on the wild side. We're also having at least six relatives from Dublin attending. One of my cousins is going to (attempt) to teach a little Irish dancing during the reception. I'll play a reel, Wind that Shakes the Barley and a waltz (?) Shoe the Donkey. I just downloaded the abc's for the waltz to learn. Should be a riot. If it's a fiasco, so much the better. We'll blame it on the champagne.
And how's this for shear luck? When I put in my year's requests for vacation days last March, I randomly picked today and Friday for a couple of them. Hence, I'm sitting here drinking coffee and I'll be getting out the whistles presently for a long practice today and tomorrow (and a long warmup on Sat am).
