Finish the lyrics: Baby, last night was hands down
One of the best nights
That I've had no doubt
Between the bottle of wine
And the look in your eyes and the Marvin Gaye
Then we danced in the dark under September stars in the pourin' rain

And I know that I can't ever tell you enough
That all I need in this life is your crazy love

If I never get to see the Northern Lights

Or if I never get to see the Eiffel Tower at night

Oh, if all I got is your hand in my hand

Baby, I could die a happy man

A happy man, baby, mmm

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
