There's a beautiful violin theme in the movie Highlander, after Connor MacLeod has been driven out of his village and is now with his new wife. It's a 6-note riff that is played very high, then an octave lower, then another lower, then finally by cello or bass another octave lower.
It's nearly identical to the New Line Cinema theme. They just dropped 2 of the notes, but kept the instrumentation and the fact that it cascades through 4 octaves.
Does anyone know whether it was by the same composer, or whether New Line Cinema just "lifted" it and made a minor modification, or what the story is behind it? I believe the Highlander theme came first (though I'm not certain).
