Today I was listening to Separate Ways, a great song by Journey in the 80s. The style of this song is so typical of the period. In fact, my first interaction with this song was through a reinterpretation by Andre Matos, rearranged and played a few years ago with a more '00s sound. Yet, the fundamental "80s style" of the song was there, and I correctly guessed it was probably a cover.
I know nothing about music theory, but yet I can perceive the 80s style. What's the technical background behind it (my guess, types of chords, scale, progression)? I don't have the keywords to be more specific, sorry.
