Thank you Balfour-Knight!
Indeed, I don’t know how, but my message has disappeared (I edited it because the autocorrector changed a word and I didn’t notice it until I sent it, maybe that’s the reason?)
Summing up, and as Balfour-Knight could see, I bought a second hand harpsicle and I’m very happy, I hope to learn just enough to start the classes with good foot but without bad habits when I can finally take them.
At the moment I have to go over the sheet music, I haven’t read in the F key for 15 years and I’m still struggling!
Thank you all for your advice, I hope to be able to continue learning and to be able to give advice like you do someday!
