Significado de "hanging to something"

Hi, guys. How are you doing?

So... I'm studying the song Green River of the Creedence Clearwater Revival, one of my favorite bands, and I faced one weird expression to me in the sentence below:

Wonder if my rope's still hangin' to the tree.

I would say this sentence this way: Wonder if my rope's still hangin' on the tree. Changing to the for on the.

Could you tell me more details about why to the has used in this sentence instead of on the?

As you can see, my English isn't good. But I always try to communicate myself in English to practice. Sorry if you can't understand me.

Thank you all!
