Well, since the synth would be blurry, I used it as a root note and arpeggiated it with the “bell” (actually, an electric piano drowned in reverb) and I don't remember if at the time I was thinking of other things with this choice, but the idea was to create some rhythm, because without the arpeggio it would be a bit boring. And thanks, the pixel art I did a bit rushed, I was late to post the song.
