The whole point of the exercise is to push yourself and by pushing, improving. The red recording light is very distracting for any one. The more you record the better you get at it. It's quite addictive.
We can be our own harshest critic. I can't count the number of recordings that I felt were unsatisfactory, only to find a week or so later that they weren't. I've stopped immediately deleting recordings.
The version you post doesn't have to be your first attempt. Listening back to your first attempt can guide you. You can hear what's missing or where a change is needed. In a live performance scenario, improv happens and is gone. Recording gives a player a second or third chance to develop a solo. I think a lot of beginners underestimate the amount of work that goes into a three minute clip.
You may not like your sound when you hear it back. however there's a lot of so called greats that I don't like. The only way to change it is to change it.
Beginner or pro, it's only music. Nobody dies but put the work in.
It's taken me several years to find the right mic and how to use it.
Taking part, beginner or pro, will produce improvements. Nobody starts out wonderful, but anyone can improve, if they aim high.
Personally I can't see the point of posting in a beginners thread. It's aiming low. Aim high. Jump in at the deep end. There's nothing done on an instrument that can't be done by anyone with practice. Put the work in and don't accept mediocrity.
