“Nervous Instrument Syndrome” also mentioned on the forum as “creeps”, “fear of the blinking red light” etc… yes it definitely is a thing. At the risk of sounding like a broken record… (ok maybe I am a broken record…) set up a recording device and turn it on and just play. Keep playing, do your whole practice session while recording, do this WITHOUT the intention of getting a perfect performance for sharing purposes. Review it later on, see where things need work or should be changed. Then do it again , and again, next several, or every other practice session. Eventually you’ll forget it’s there and it will be easier next time you wish to capture a video to be shared.
By the way, went back and rewatched the “Practice Time” video in this post… and then the Swiss fun song video. I REALLY like the chimes you did on Mountain Dew, and the ‘fun song’ reminds me of my Dad and brother doing old French songs with guitar, accordion, and harmonica… I couldnt understand the words in the French songs they did neither the words in the Swiss song - took me for a trip down memory lane!
