I don't often record myself and listen to the recording as I'm learning a piece (separate from recording a finished piece). I find it both demoralizing and time-consuming. I know I should record, I really should. Shouldn't I?
These types of recordings are of a work in progress, not a finsished product, and we've grown accustomed to having everything sound perfect. That certainly can contribute to the ego bruising, but the majority is from hearing all the flaws in one's playing. Then there's the time aspect. Recording and listening back has a cost in time.
For those who regularly record while learning a piece, how big of a chunk do you usually record? Or even if you don't regularly record, what amount do you recommend? I'd ask for recommendations on the ego bruising part, but there may be no help for that.
