Thanks Desordre, I had just about given up on getting any feedback, but yours is really constructive and helpful. I too used to play classical guitar but gave it up 6 years ago and traded my John Mills Concert model in for my Yamaha CLP970 digital piano, a decision I have not regretted. I studied piano up to age 15 (grade 6 I think) then didn't play for a lifetime of work - 50 years. I am now trying to get back to where I was 55 years ago but it's not possible. However, I am slowly improving, hence the post. I totally agree about Sor, he composed some wonderful guitar music and I have a number of CDs which I still listen to. I didn't realise he had actually been influenced by piano music to any extent.
I realised that my playing was a long way off perfect but had decided to post something to get some critical analysis, which you have given me, and also hopefully get some feedback on the quality of the recording as I have only had the Zoom H4 a short time.
Regarding your observations, I know I made a bit of a mess with the last variation, regarding the speed I initially played it faster, then heard a guitarist playing it at this speed so decided to record it like that, a mistake I think. I'm pleased you like var. 4, it's so beautiful on guitar that I just tried to match it.
Regarding pedalling - believe it or not but when I was learning as a child my piano teacher would not let me pedal at all! and I passed all my exams without using it. The result is that now I am trying to teach myself correct pedalling and, at the moment, I know I generally use too much - I'm working on it.
Thanks again for your post and maybe we can, as you say, exchange more ideas. I live in England by the way.
