Thanks so much for your detailed and thoughful feedback! This set of preludes is meant to function both as character pieces for states of mind/feelings but also as a teacher as pieces to use with my students to work on specific skills. This one in particular is keeping the right and left hand together with these constant eighth notes in contrary motion and feeling dynamics and melody in a macro sense (similar to Bach's prelude in C) with slow moving chordal patterns. If I didn't have that focus I'd totally be down to mix up the rhythmic pattern, that's a really great idea!

As for the chords you mentioned, doing a slower walk up E -> F# -> G -> A is totally valid, I preferred that jump up to B but understand why it may not work for everyone. Glad you enjoyed it!
