[Dixielandjazz] Melody/chords

[Jim Kashishian]

We recently decided to try out "Are You Lonesome Tonight", and while I was
quite happy with the mid-tempo song (we don't try to do an Elvis copy!), the
chord guys in the band immediately shouted "When You're Smiling in another
key", and have basically written the song off as a copy (although it
actually comes from before Smiling).
 
This brings up the subject of those that "hear" songs as chord progressions
vs those who first hear a song for its melody line.  Obviously, your
instrument is going to somewhat dictate which side you tend to.  Are there
any stronger arguments for which comes first, the melody line or the chords?

 
For the general public, I would say it is the melody, and even the words,
that are the most important.  There is a Spanish songwriter/singer who is
very popular although you could never whistle or hum one of his melodies.
It is his words that make an impression on people.  In this case, melody is
less important, and chords would be way down the line in importance.
 
How about our music, though?  I hear a song by its melody first, later being
interested in the chord progressions.  Do others have an opinion?
