>>92707726>>92707726Cool. Yeah I don't know much about jpop. I'm glad we can talk music theory bullshit though.
It's not the key change itself that bugs me it's that it's set up strangely. As the verse ends they are building up a bunch of tension on the V chord and you'd usually expect that to resolve back to tonic but that's where it modulates and the next chord isn't even the tonic of that key (bVI I think which is bII of parent key).
I guess it's cool that it's surprising but from bach to jazz you would handle that very differently maybe in this case using secondary dominants ie V of bVI in the chorus key. I dno.
