Fingerings for Prelude and Moonlight sonatam.1

[carmstro64]

Greetings I am a piano student. I've taken previous piano classes. But I am still a beginner somewhat. I'm strong at reading music being in band for so long but I need help with understanding the fingerings/musical symbols for the following songs:

Prelude in E minor, OP. 28 No. 4 (Chopin):

What does the side ways "S" in measure 16 mean? What do the consecutive numbers above it mean (4312) as well as the double sharp looking sign below it?

Moonight Sonata, movement 1 (Bethoven):

Measure 30, the first two notes,
Do you just tap the first E and quickly move your thumb to the following E? Or what would be a better approach to that jump?

Thanks alot,
Christian

As for the prelude, it means you play with fingering 4312.
If i recall correctly, the "S" means you play H(4) B(3) A(1) B(2) numbers are fingering.
I might be wrong about the notes, so don't take my word for it, don't have the sheet here. Check for my description in the other reply.

And yes, for the Sonata I would jump with the thumb from E to E.

To clearify what the S means, it's referenced to as a "Turn"
Also known as a gruppetto, a turn combines an upper mordent and a lower mordent, in that order, into the specified note's value.

Right notes but the actual spelling would be B natural, A#, Gx, A#.  Point being that the x below the turn is to indicate that it should be Gx as the lower auxillary.
