Prelude No.2 in Cminor

He is talented but the time one of the guitars wasnt plugged in? or was it wireless or something?

This piece was written for a clavichord and not for and expressive instrument (piano forte for example, and bach never liked it,,,), thus Gould's interpretation is original but not how Bach's probably meant it to sound like..

No, it was written for a clavier, which is a general term for any keyboard instrument. And Bach thought the pianoforte was amazing when he heard it.

According to history he did not. He much preferred his harpsichord.

Clearly, one of us is wrong. Can you give me supporting evidence? (I can't :P)

This piece was originally written for the Harpsichord. Bach originally did not approve of the early pianoforte instruments, but near the end of his life, did in fact like the newer ones (the Viennese Piano).

Right, I'll buy the thing about how he liked new pianos, but you're wrong about him having written this for the harpsichord. It's for the clavier - "The Well-Tempered Claiver," see? - and some of the pieces can only be played on organ, so clearly he had that in mind sometimes.

The term Clavier is become misused for the Clavichord. Clavier comes from the German word Klavier which refers to ANY keyboard instrument from the Baroque era onwards.

Also, this piece was never intended for an organ, as it was to be played on a well tempered instrument, which means that the instrument was tuned with equal Hz distances.

Yes, this is right - by clavier, I meant 'any keyboard instrument.'

I'm not sure about the organ - but why can't an organ be equally tempered? And why, if he wrote things that can only be played on the organ, did he never intend it to be played on the organ?
