Hi! The full video with explanations is on my YouTube channel here https://youtube.com/playlist?list=PLVD3cc-hjPwAcyluCXfGjVetzwbF8GSSt . Recently I’ve found out that YouTube and Instagram were deleting some of my videos because of supposed infringements to copyrights. In some instance (impossible to check on old suppressed content), I suspect that the music came from my daughter playing the piano behind me. Actually the leash is a bit short for artists. Sometimes your entire profile can be suppressed for days without warning and any possible appeal. That’s why I’ll cut all sound in future publishing, it’s safer! But even like this I don’t feel safe on these platforms... that’s the meaning of this blog, a respite and hopefully a real place to speak.
