Splitting Posts Into Different Sections

I have a website (blog) about hip hop and I am about to add Film and sports to it. I was wondering how to make it so posts only show up in certain sections on my site. Like have hip hop posts only show up in the hip hop section and sports posts only show up in the sports section and not on the home page. If anyone knows please help me! Thanks!

P.S. If you need any more clarification let me know.
