"how music effects math skills," what thesis statement for research paper

My topic is how music effects math skills and the name of my paper is "Rock Music vs. Classical Music:
Their Effect on Simple Math Skills". I can't think of a thesis sentence at all.

Well first I would suggest coming up with your examples and proof of the subject. Then work on your thesis.

That's because it makes no sense to make a general assertion about the effects of music on math skills. This is an example of an idea for a paper that involves too much...

Maybe you have seen some articles about classical music having positive effects on brain development. If this is where you got the idea, I suggest looking at the articles about classical music and add your own theme.

Make a unique contribution by suggesting an idea about rock music that is related to what researchers have said about classical music.

The repetitive and mathematical nature of music lends credence to the view that those skilled in music are also innately skilled in mathematics
