When it comes to representing sounds in the song, try and listen to the song and place notes in appropriate timestamps as you go along — there should be some mapping tutorials out there which could help, but also taking a look at other mapper's maps and taking inspiration from said maps are also beneficial as well (Or at least, in my opinion). It is healthy to learn a bunch of mapping styles and techniques for when you chart songs for versatility and flexibility in your skill, so don't be afraid to go out of your comfort sone for mapping!
