SOPP547: I was never taught early fingering

This question was sent by J. Flemming. He writes, Although my teachers have stressed the importance of articulate legato in playing Baroque music, I was never taught early fingering, so it is very easy for me to lapse into familiar patterns (like crossing my thumb underneath my fingers). I am learning BWV 659 (ornamented chorale Nun komm, der Heiden Heiland) with Vidas’ fingering, and it is taking more repetitions to get used to the fingering. The results will be worth it, though. I expect to be able to play this in a service before Advent is over. It’s been a good exercise in developing the discipline to do it right instead of quickly.
