The mod, or modulation (changing keys), in song arrangements has been around for a long time.
One of the more popular ways it’s been used (and maybe overused) is modulating at the last chorus, typically up a half step, or a whole step.
Celine Dion went to the bank doing this time and time again, most dramatically in her remake of “All By Myself” jumping up a minor 3rd at the last chorus! (Be careful using this idea in your song; only a few singers can sing this kind of range).
Enjoy!
