We're all Synesthetes

[faulty_damper]

Synesthetes, so you aren't really all that special.  Never were.  Apparently, we're all synesthetes because we can match mood to music with surprising accuracy.

As for why?  Here's a hypothesis.  Visual and auditory information is processed as frequencies, vibrations and electromagnetic frequencies.  Our brains interpret these frequencies into sound and color.  Somehow, a sound frequency triggers a similar response in the visual cortex which corresponds to certain colors.

Think of what color(s) match these examples:
Mozarts Flute Concerto in G
Mozarts Requiem in D Minor

Then visit the article page to see if your response is similar to most peoples.

Green and red, so not even close.

"Major=happy, minor=sad" .... ok .... Is there a chance that maybe those common answers are a result of our black and white educational systems in school, family, society, etc.?
