I'm going to use the title "Easy Recording Tricks #__" for just simple easy little things anyone can do to get better recordings, no matter what sort of gear they have. 

The Doubletake -  When you are all set up to record and you hit that record button, never ever do just one run through the piece you're trying to record.  Do two of them.  Do the first one, then pause for about 10 seconds and play the piece through again. 

Most of the time, you will definitely like one of the two times better than the other.  Maybe you played a little better, or whatever.  But I would bet that most of the time you will have a clear preference for one over the other.

So pick the one you like best, and highlight and delete the other.  It costs nothing, it only takes a little longer, and it doubles your chances of getting a recording you like. 

So, if you start recording and you mess up, don't stop.  Just think "Oh well, we'll try and get it right on take 2."  Especially for folks with a bit of recording jitters, it can help.

Seriously, simple and silly as this tip sounds, it can save you a ton of time.  

And yes, this absolutely goes for recording video as well as audio.  If you do any talking to introduce the piece or whatever, do it all for both takes.  You will probably like one take better than the other, and even if the talk of one is better and the playing on the other is better, you can edit to to get the best.
