The best way to begin learning music production is to start discovering a Digital Audio Workstation (DAW).
There are free and premium DAWs but you can download free trial or free versions of premium DAWs for experimenting.
Once you decide on your primary DAW then you can watch tutorials and then start discovering the DAW itself. You can discover the loops which are given with the software or you can download free sample packs from various loop sites or sample companies.
The most important thing when you start learning music production is not to over-watch and over-read.
Don’t forget, the only way you can improve yourself is to practice.
