F cleff switches place on sheet?

[kirl]

Hello all,

I am writing a computer controlled piano player and it's working pretty nicely, so I am now busy putting in sheet music in the format that my program accepts it, but I am uncertain how to proceed.

Above is the youtube sheet music that I am trying to put in. At around 1:24 you'll see the f cleff changes place, and now I am unsure what happens to the left hand? (where the f cleff was located previously).

Should all notes drop places? Or do the bottom notes stay oriented the way they were?
What are the first few notes after the cleff change?

Don't think of it as the clef changing places.  Think of it as the top staff changing to f clef.  The bottom staff will continue to read exactly the same as before.  So in fact they both represent the same space, but for different hands or different voices.  He just changed the clef for the right hand to avoid using a bunch of added lines or dropping it into the bottom staff.

Thanks for the clear explanation!
