I've found this is BuxWV 140, actually called just Praeludium in d. It is a multi-part piece, consisting of a short prelude, a fugue, a recitative in the stilo fantastico, and another short fugue in triple meter followed by a brilliant fantastico coda. A strange but very compelling work, showing off Buxtehude's unique combination of fantasy and mastery.
Prokofiev bails out at the end of the first fugue, tacking on a convincing ending of his own making. On one hand this is a shame, as many great things are yet to come. On the other hand it's now more like a regular, Bach-style prelude and fugue, and it's rather more balanced than Buxtehude's original sprawling invention. Your slow tempo works very well I must say, it makes it a different, almost meditative, piece.
Intriguing that Prokofiev was apparently acquainted with organ music, and chose this work rather than something by Bach which would have been more obvious. I think he did a good job on it, staying faithful to the score. Based on this transcription I thought this was a nice small organ piece to learn and play with services, but it's a rather more fierce creature when taken in its entirety and played in true baroque style. I think I'll pass on it for now.
BTW Rich, your spelling sux... The composer is called neither Buxtedhude or Buxtuhude
So now the question, where do we put this - under Buxtehude or Prokofiev ? Transcriptions still faze me.....
