If you can remember it after a couple of weeks it stands a chance that somebody else might remember it also.

On the performance thing, i taught a friend (total beginner), to play a couple of tunes. Then he went away and learned a few more. after a while he was playing on my porch with his pals who had also learned his tunes. They asked me to join them and i refused because i didn't want to spoil there sound. It was totally real and magical (and humbling), to listen to folk who had learned a few tunes over a year or so, just loving the fact that they could play together.

i went away with a (probably self indulgent), warm feeling that i was in at the start of their joy for music....lovely.

IMO If it is honest and real it will sound and feel  good to you and others, no matter what level of playing you are at.

The best advice I ever received from one of my 3+ violin/fiddle teachers was to listen - listen to really good players, listen to yourself. Identify what's good and keep doing that. Identify what's not working well and learn how to fix those things, one at a time. I took time during the years we mostly weee forced to stay home, to focus on quality. It's paying off.

Record your self. Is it good?

It's interesting how listening back to a recording of yourself is so much different, but it is. Listening to oneself in real time is like watching smoke, or something. Another thing I learned by recording is how your tone is important. They say, tone, timing, and taste. Each is important. None of these are really subjective if you're playing in a group. You are either where you belong in the music, or you're not.

With recordings , I always have this: first few listenings I think Yay! I nailed it! BUT then after a while I put the same thing on again, then I notice where I go wrong at which places in the tune and what can be improved. Sometimes some mistakes became a habit and then I have to undo this by zooming in on the details and practice the correction of the mistake first very slow then after a while speeding up is the next step.

No matter what I do or think, I will always be kind to myself. I have reached it this far and that tells everything about me. How many people are there that quickly lose their belief in what they can do or reach in life? Way too many I guess. So as a consequence there are too many homeless beginner instruments, bought and left alone when it became difficult.

I just buy a new fiddle. My playing isn’t very good but I’m getting better at spotting a good fiddle I’m up to fiddle #12 and with a bit of a tweak $400 strings and yet another new bow I think I’m getting somewhere. Still searching the classifieds every day.

I trust all the people who have asked/hired me to play gigs with them, if I'm good enough for them, then that's good enough for me. But, to me, fiddling is a never-ending journey searching for that ultimate skill, in any genre chosen. Every day I make improvements at my skill no matter how slight they maybe.
