Well, I have "Settling The Score", and she writes that the melody is a major progression over minor chords.....which isnt at all correct. She said the melody sounds minor even though its major. The first chords are G minor, Eb minor and then back to G minor. If you dont believe me, just check out the sheet music or score. well.... actually, this is right. the first phrase of the melody (the first 9 notes or 2 bars) which is very characteristic of the Imperial march theme goes like this : G-G-G-Eb-Bb-G-Eb-Bb-G if you watch this carefully it's just an arpeggio in Eb major! (Eb-G-Bb) But the harmony beneath is minor as you correctly said. So, we indeed have a major melody sounding minor because of the harmony. that was what she meant I believe.. and also, about that La strada theme. It's indeed generally accepted that downward notes motion symbolizes sad feelings.. but of course this is not the only reason. many things play a role, like the context in which this motion belongs to, the harmony, etc... I hear what you're saying. The problem is, the ear hears G as the home note so in a fixed 'do' scenario G (la) is the tonic. That in itself makes the melody sound minor. You don't really hear the G as 'mi' Mi is only the tonic in Phrygian mode.
