Nicely done.Timing is good generally but the tempo fluctuates a little. Those last semiquavers in the bass are semiquavers, not the quavers you played. You can do a rit, but don't change the note values.
Bach is blessed and needs to be treated so.
Both ideas would horrify him. In practice, go as far you like. You can't break Bach. In performance, you'll then know the boundaries and can flirt with them. There are all too many reverentially timid performances out there.
Cannot listen now, but will do later. Ritardando means slowing down the tempo intentionally, usually done at the end if the piece. Or if indicated by the composer.
Thanks for sharing this On bar 13 on, i would try playing the upper voice like the bass in bar 9, since its the same motiv,so either i would either try to play both staccato or both legato (that being only my opinion).
Listened to it now... just work a little bit on the tempo issues and it will be good. Have you tried counting in your head as you play?
Are you sure? I meant what I said about Bach being holy. So I guess you're saying it's okay to improvise, but keep to the time of the bar/note/technical wise.
