Hello! I'm relatively new to music theory. I'm really racking my brain trying to justify this Chord progression from Sam Smiths "I'm not the only one" It goes F major to A7 to D minor. I'm confused because how does A7 fit into F major? It has to have something to do with modal interchange, but I just can't figure out what. How can you just borrow that c#? Anyway I came to thiby Kellie - Music Theory Questions and Answers
