>square things
I don't see square things. If you mean ,then they are called sharp signs (or diesis), see

If you mean the black lines, beams or flags.

I mean these beams, hanging*** from the notes

What do they do?

Not a musician here, but I think that they depict two sets of notes, either played at the same time by different peoples or played differently in the repetition (you see two lines of text).

oh, this is it, thanks. Now it's so obvious, the melody matches the sillables. It's just that there are few of these in the whole sheet
