@FlytrapStudios The time signature actually only really changes at the end. Holst just writes to make it sounds as if the time signature changes... it stays in 6/4 pretty much the entire time, but it has a 3/2 feel in some sections.
It goes into 2/4 not 4/4. Either you don't have a score or is it printed differently in other editions? Kudos for noticing the theme in the left hand at measure 32. Beethoven is brilliant.
This was an epic moment!
