Bach - Prelude in C minor BWV 546i [Learning - Day 3 - High speed check] Tempo=104

Описание: This is my third day of learning this piece.

Today I've used the brisk tempo of 104 (quarter | crotchet):
1) To ensure I have the notes fluently and fluidly in my mind.
2) To ensure I'm thinking about the piece melodically (horizontally), not in chords (vertically).
3) To see whether it works at this tempo e.g. in terms of keeping the listener's attention without sounding manic or scrambled.

Maybe this is how Bach played it?
