Another P&F that I adore but can barely read through: the P&F in G# minor, WTCII. What skill Bach displayed in layering sequences and modulations and themes in a sonata form, and keeping the listener (or reader in today’s case) spellbound. I am frustrated only in my inability to accommodate the key signature and the modulated double sharps instantly. The fugue is a grand, masterful statement in three voices, four pages. I find it nearly easier to read than the prelude.
I am staying today with a dear friend, and playing on her beautiful old Steinway A, from her Henle edition of WTCII, where (happily) she has lightly penciled in some of the more challenging sustained accidentals. And some fingerings. And arrows to the fugue subject statements. What a delight.
