Is this chord progression in C major, A natural minor, or some other key? I'm not even sure myself, so it would be cool to get other musicians' opinions on this. The chords are: ACEG, FACE, EGBD, CEGB. In the audio of this chord progression, I've made three different rhythms for it (each rhythm plays twice). The third rhythm is inspired by the MTT Resort themes from Undertale.
