What If Classical Composers Wrote "Body & Soul"?

This is a fantasy on the idea of what this song might have sounded like if it had been written by classical composers. It has four sections, and each one is hiding one of them. I’ve always wanted to try a game like this, since I belong to both worlds — jazz and classical music. Can you guess all four? Listen to my album "Fathers" https://linktr.ee/anna_zavorina
