Hoi Hanspeter
Is English the common language in this guitar club, for a better understanding for all ?
You are a musician, a genuine professional, I like your work. About your request for our opinions: IF I would be that far that I could play one song on guitar, I surely would join that test program. But my knowledge in this instrument is near zero 😔
My love for guitar and piano music is real, but... I never ever started any guitar lessons. In 1986 I bought a 70 dollar guitar (in Germany) and since then it survived many home / place movings and got dusty, but not rusty. Deep in my heart I never gave up on my vision to start playing guitar one day. Never had the right leisure or time to start, but as some things have changed, NOW I have time 🙏
So I want to show up here sooner or later, I think, no later than June, but I have to pass some exams until end of May. Your willingness and time assumed, I would start online lessons via Skype with your help. It is time to do the better things in life.
You can train absolute beginners, I am convinced of that. For the Guitar Certificate you can ask me 1 year later 😂
Blessings
