“Hi Vidas
Very good wishes for you both!
I want to tell you that I am studying this wonderful Praeludium in C from JS Bach, using your tips. Especially the tip cutting the piece in 4 bars and not making any mistake by playing slower, it’s working! In fact it goes faster and it’s giving me a lot of pleasure, thank you very much!!
I will support your beautiful work of course.
Greetings from Groningen
Rolf”
