Welcome to BWV 881, F minor from WTCII. In WTCII, both the F major and F minor P&F’s are a couple of gems. This P&F in particular looks forward to the classical era; I think Mozart must have been channeling Bach in his Sonata in F major K. 332. The use of sequence, especially in the fugue, is perfect. The prelude has such a strong, mysterious character. In spite of the four flats, this is accessible sight reading. Give it a play through; you’ll be delighted.
The photo above is also about Bach in F minor, albeit 857 from WTCI. I had the pleasure of hearing this recently graduated student play the WTCI F minor Prelude today at my church’s organ. She was the paid substitute organist for much of the summer. It’s very rewarding to go to church and hear the organ as you get out of your car and think, “that’s my protégé!” The priest gave her a blessing for heading off to college next week. A sweet moment for all of us.
