Synesthesia and Cymatics

Synesthesia

I have heard about synesthesia before, but I'm not sure where. The closest my experience has gotten to synesthesia has been either when I've stayed up too late reading and the words start turning colors, or when I'm getting a migrane.
I think that synesthesia is such an intelligent phenomenon of the neurological impulses; perhaps those who learned certain subjects would not have been able to with out their case of it! Although that is difficult to determine, imagine if natural selection occurred and that was the normal thing for a brain to do to learn more effectively and efficiently. People could potentially learn more languages, subjects, or sports--and it would be a common occurrence!

Maybe through studies and film experiments this neurological phenomenon could be acquired as a child watching TV programming. Like Little Einsteins (or is that the attempt already in process?).


Cymatics

Does cymatics (the visualization of soundwaves) have to be scientific? Could a soundwave be subjective? Perhaps there is a specific pattern in each soundwave moving through space, but like two people cloud-gazing, they perceive it as a different experience.
This creates a spark of curiosity inside my head because this is the way film should be portrayed and discussed--how else would we learn about human experience! I remember coming to UNCW with ideals about how music videos are ultimately the most powerful for of media through the art of persuasion...

 Are there subtitles/PSA type music video? Credits with information at the end?

Logistics/linking research and topic back to thesis

When sound and image syncopates on film, the creator has the opportunity to create a powerful impact through their use of editing. But, both aspects have to be on their game: both song and editing must have a climatic point of power, i.e. key change. Top five songs with amazing key changes/peaks (don't judge, this is purely on the key change's impact):
5) "Thong Song" - Sisqo
4) "Love Story" - Taylor Swift
3) "Shake It Out" - Florence and the Machines
2) "Countdown" - Beyonce
1) "Old Pine" - Ben Howard
With "Livin' On a Prayer" - Bon Jovi as an honorable mention

I believe we as a generation could further cymatics as the visualization your mind creates when listening to moments of impact, almost like living out your own personal music video.
