Favourite WTC prelude?

I really like these ones=

No. 5 in D major
No. 2 in C minor
No. 3 in C# major
No. 21 in Bb major

Bach was a genius. His melodic ideas in these pieces are captivating.

No. 1

bb minor #22 book 1

book 1:

-da Meph

no.4 is tense.

one of the greatest fugues ever.

No. 8 is probably my favorite. By a long shot.

NO 3

the fugue in that is a beast.
