How I play the Genshin Windsong Lyre - The Cab - Angel With A Shotgun

Instructions:

The capitals are for the melody.
The small letters are optional if you want to add some 'harmony' to it.
Keys in the brackets [] are to be played together.

Disclaimer:
I am still trying to figure out a way to present the note in an easy way to understand, because I write them down on paper for myself adding some additional signs that I guess only I could understand, so forgive me if you don't understand the 'notes' ;/
