I was watching this video, and I found it extremely interesting. I love Persona 5's music, and just music and music theory in general. I suggest this video if you want to learn more about what a major and minor key sounds like that sets the two apart, even if you don't like or are not familiar with Persona 5.

If you want to know what instruments I play, I play flute, piano, ukulele, a little bit of guitar and bass, and I sing.
