You’re on the right path and in the right spot to learn.

Best way to learn how arrangements work is to listen what your favorite artists do. Literally, dissect the songs you like and listen carefully when each element comes in and how they evolve. What happens to create tension? How is the tension resolved?

Simplest way is to add layer by layer. Open up filters or increase reverb length. Stuff like that.
Do that while jamming.
Over time you’ll get a feeling what elements need to come next and how long you let the groove roll till the next element comes in.

What do you feel is your biggest hurdle right now in building arrangements?
