S. Wagner piano (organ) sheet music

I have found several pieces which can be performed either by organ and piano players. And this is specified by author – composer Serge Wagner. All this pieces are quite short – one – two pages. And all of them are appropriate for exercise. Difficulty level varies from easy to middle.
The discussion about is it normally or not that we play compositions of J.S. Bach and other Baroque composers by the piano although they were written for the organ or the harpsichord lasts for long time. I think - from the time of the creation of a piano. Yes, the nature of these instruments is quite remote. And as result an interpretation and a sound of the same composition played by organ or by piano players will be always various. I have heard the audio recording of one Bach’s piece performed by Glenn Gould in one case on the piano and in other case – on the organ. The tempo and the interpretation in the organ variant were absolutely different from the piano performance. Of course the time period between these recordings can be the reason of this, but I think that facilities of these instruments – piano and organ - have played theirs part.
This is why it seems to me very interesting to take a look at Serge Wagner’s pieces. In some of them he has specified that it is possible to play them by Harpsichord, Keyboard, Organ, Piano, Reed organ, Synthesizer. If you play any of these instruments you can visit the page of Serge Wagner and download his sheet music for free.
