Ordinal Prime Sequence?

[Ya Boi Martel]

I am trying to solve the last puzzle I need for chapter 3, but I am very confused. I know the game gives you hints about how to do this, but my brain is denser than a brick and I am completely baffled on how to progress. Could really use a hand.

2 3 5 7 11 13? I think there are enough keys to go up to 13. Numbers that can only be evenly divided by 1 and themselves.

The next ones get worse, but the worst part is the hints get much worse. I lost to the later puzzles and just looked it up..

Thanks Du-vu, gonna be honest, forgot 2 was a prime number, like I said I am dense sometimes

They do get harder Halfshell, I feel stupid saying it but I am now stuck on jingle bells.

The jingle bells hint is the worst. Mostly because it gives this useless hint about the first note being C or something, which as far as I can tell cannot be helpful in the slightest.
