The main theme of the chrono series

[HeadlessFritz]

I was listening to the chrono cross soundtrack and wondered : what is the main theme of Chrono ? In the song Field of Time you can hear, at ~20 seconds, the same song that plays at the end of the chrono trigger intro (after the pendulum). This is also the song that plays in the CC intro song (alternating with Another World music), The dream that time dreams. Yet you can also hear Crono's theme in Field of time. Is Crono's theme the chrono series main theme or is it that other melody in both game intros ? Or both ? Just wondering. I was really happy that Mitsuda re-used that melody in CC. It gave me chills back then.

Well it all started from a leimotif in the CT intro song, track 2 disc 1, labeled 'Chrono Trigger (Chrono's Theme)'. Mitsuda based the entire CT score off that one song. I can't recall the exact interview that he said this in, but I'm pretty sure it's the same one that they addressed the Robo Astley phenomena.
