that kick hits weird, I like it! I feel like the lead fits in, but IF YOU WANTED TO, you could add maybe more than 2 chords. ITS NOT NEEDED THAT MUCH THOUGH. and one more thing, an arp would sound great in this, not a loud one, but a background.
I have to agree with
@itxmi
. Hardly any note fits here. po9t was kind enough to mention that it’s in A minor. So, you could google it and check which notes would work. Or do it like me—someone who (unfortunately) has always avoided music theory—and go bar by bar in a loop, figuring out which note matches the part of his vocals.
