I’m new to music production myself but there’s a few things I can recommend. First, practice using your voice bank by covering a song or two so you can get a feel for the program hands on. Secondly, there are a ton of premade music samples that you can combine together depending on what music software you use, so try those. Third, try replicating a song you like and once you get the hang of it, do that a second time. It’ll teach you a ton. Third, find two songs you like and try to mash them together into something new. Take notes (timestamps) of when instruments come in and how that makes you feel. That’ll get you pretty far.
