Last night, I figured out the violin in the choruses of the orchestral version of "Walking in the Sun" (although, provided I've figured out the parts correctly, the violin arpeggiates different chords compared to what the guitar plays).
In any case, while figuring out the part, I realized something about the melody to which the title phrase ("We'll be walking in the sun") is sung. Here's the notation from an old post (it's actually the French horn part from the orchestral version, but that just doubles the vocal part):
This is a conjunct phrase (it moves step-wise through the scale), so musically, there's a sense of that "walking."
