I think youre right Chris, we are all too hard on ourselves but at the same time we need to keep some perspective and have a clear ear. Every performer has a sloppy moment, but we keep smiling and rock on. Thats one aspect of learning. Hear the mistakes and learn from them.
I personally would love some honest feedback instead of all the polite praise. If you hear that a bend is slightly off or a note in the wrong place or timing is off then say something. { I hear those things in every performance I do) Always in a positive way, but isnt that what we are here to do. Manicure our performance and constructively support each other? Why are we so frightened to say what we really hear. Isnt this the forum for it? I would respect other muso's much more knowing that they have an ear for music and could apply it.
On a serious note 😁, you are so right about the balance of forgiveness, the beauty of sloppiness, and the need for constructive criticism.
Perhaps such comments are more easily shared through PM, and then the contributing artist could share what remarks were poignant, helpful or eye opening A-Ha moments. The reviewer could even annotate their forum post giving general support with the critical hint- PM sent. I suggest this to keep things positive in public as the open airing of critique may intimidate newbies or spark a , "what you say?!!" moment. My 2 cents.
Now, where are my fighting trousers?
