The reviews seem to have finished, so I will say a thing or two, trying to address all the points you so helpfully have raised.
As Chris and Andrew say, the piano is bad and one reason I held back so long was considering its quality. Mind you I have found recordings here where the piano seems out if tune, for example. I believe them to be old ones, however: all recent recordings I have listened to seem to use good quality concert pianos. I agree I need something better and, yes, it is a bit frustrating working on this one. I remember my only teacher, many years ago, told me a bad piano can actually harm one's technique. The smudges that Monica mentions seem to be part of the piano. I tried hundreds of times and in all of them I heard the same noise. At times I seem to hear a vibrato, which I am sure is not right. Can this be remedied? Not really and at present I cannot invest in a new instrument for one reason or another. At least it is rented, so getting rid of it will be no problem. The problem is that good quality pianos are not for rent where I live.
I am not sure how I can improve microphone placing if I have a portable Mp3 recorder. Is it possible to attach stereo microphones to it?
I could also take the piano to pieces, but then, where do I put the score?
Andreas seems to like the tone, however. Is this liking something German? What reputation do those pianos have in Germany?
I cannot fathom how a digital recorder can have tape hiss, but there you are, it has. It bothers Monica and she is right. Having once edited the noise with Audacity (and submitted), I was in no mood to repeat the experiment. Andreas, however, seems to be able to split hiss from piano with no damage. Thank you for that work!
Several of you mention the right hand in The Butterfly and this is a good point, though I am afraid with an upright the risk is depressing the keys and no sound coming. The same applies for The Angel.
Adrienne Says the Camilleri could be faster. Indeed, on the score the indication is "about 2 minutes" and I have a take where it lasts 2'10". I have only heard it once (it is on YouTube as an illustration for the Trinity Examination) and there it lasts, I believe, 2 seconds less than my version.
In The Angel Andreas says it sounds like a Hymn. But that was my intention! The score indicates at that passage "Chor der Engel" (Choir of the Angels). Or perhaps Russian Orthodox angels do not sign hymns... I will, however, experiment with your suggestion.
I would say I tried my best to be perfect: I recorded virtually hundreds of takes of each piece over the last two weeks and I believe this shows. The fear of hitting once more a wrong key is the sure way to hesitate before a passage that I know by heart. After all, this is my introduction to you and you have no idea how I play and you must judge from what I submit this first time.
One thing I omitted to say (on purpose) is that all these recordings were made after I suffered an accident in the street and broke my right ankle, which is now in a cast, so all pedalling had to be done with my left foot and the arm position, of course, had to shift ever so little. In The Angel whenever I wanted to use the soft pedal I had to give up the sustaining one. Happily this was not an issue. I surely wanted you to listen to my recordings for what they are worth and not to sympathise with me. My next recording will hopefully be made under normal conditions.
Here is a link to some of these pieces, which will allow some comparison:http://www.youtube.com/watch?hl=en-GB&v=5IF2poGK68Y
Again thank you for your helpful suggestions. I shall keep trying!
