Sinfonia in B minor BWV 801

This is a re-upload of a piece that was deleted in the website update
The last of Bachs 15 3 part sinfonias that he wrote for keyboard. I usually play this on a piano but I thought I would try it on the organ, and like most Bach pieces it works very well I think.
The piece is in B minor, a key that Bach was evidently fond of, for many of his pieces and some of his very best music is in that key.
The timing is in 9/16 which is quite an unusual time signature and the piece is built on a 3 note motif which is imitated and then gives way to a flurry of 32nd note arpeggios.
before the theme is repeated in invertible counterpoint. This pattern of variation, repeat and invertible counterpoint is conitinued till there is a shower of 32nd notes coming to rest on a grinding E sharp in the bass, before descending to a perfect cadence. The idea of the Sinfonias was to teach people the playing of pieces in 3 parts.
Tempo wise I have taken a rather slower tempo than many piano recordings. This is because I believe that fast in the case of this piece is weak, as Bach said that the Sinfonias were to be played Cantabile, that is Singable or Songlike.
