Prelude in E flat minor

["BONG" <bong@iti.lt>]

What about this one? Its performance by Gould differs hugely from all the
other preludes: very choppy, full of abrupt stops, very different from other
performers' fluent manner. Is it because of those dots near notes (yes, I'm
a layman:)? Or maybe it's all about Gould's interpretation?

One more question: did Bach deliberately compose preludes in such strange
tonalities (E flat minor, plenty of flats...) or did he simply transfer
notes from a more regular tonality?
