ShiroKuro I think youāre being hard on yourself! I know you posted the ābest of,ā but it sounded more than creditable (despite the out-of-tune-ness of the piano). As @Ithaca commented, thereās something special about the effort of an in-person performance, and Iām sure your audience appreciated it.
Give yourself a big pat on the back for doing this. I think it takes courage and commitment to get on a stage and play in front of strangers, and you will only get better at it by doing it. I know that you love this music, and I think the wonderful thing about playing for others is sharing something you love (and that youāve put a lot of effort into). I am sure you conveyed this to the audience in your playing, and Iām sure they appreciated it.
On a different note, I will venture to guess that delta between this performance and the you were really happy with may not have been as big as it currently feels. Iāve had the experience of recording things and being really really frustrated with myself and feeling like I really really botched it. Then I finally get a take that in the moment seems pretty good and that I feel happy with. Listening back later, though, while I usually agree with my assessment about which was the better recording, Iām often struck by there not being nearly as much difference in the quality (the bad ones werenāt so bad and the best one wasnāt so so great). I also find that with time, my feelings about a particular performance change ā and Iām not as hard on myself with a little distance.
