Need help finding a certain piece

[svensknavi]

Hello. First off, if this is in the wrong part of the forum let me know and I can remake it elsewhere.

Long story short, I'm trying to figure out the name and/or composer of the first piece I worked on in my piano lessons. All I can seem to remember about it was that it is a single page piece, that the second half of it repeats once, and in the second half the left hand is doing octaves (like a really slow tremolo), and I believe it was staying on the same note for the entire duration. It'd be probably a level 2 or so piece (using piano street numbering). My teacher thinks it might be Haydn, but she can't remember either and doesn't have notes going back that far anymore, and so far I haven't found it looking at Haydn pieces.

If anyone has any ideas, that'd be awesome. Thanks!
