   Myriad, unfortunately I know very little about music theory. But I have looked   
   up some articles with explanations of major/minor scales and chords, and it   
   looks like there is a bias toward lower frequencies in minor scales and   
   chords. I mean, when you    
   take a minor scale and a major scale with the same root tone, the average   
   frequency of tones will be lower in the minor scale than in the major scale.   
   Same for minor and major chords. It fits with my intuitive impression that   
   sadder/darker songs seem to    
   have "kind of lowered" tones than happier/brighter songs.   
      
   Of course, you can have a minor scale that has a higher average tone than a   
   major scale, if the root tone of the minor scale is higher than the root tone   
   of the major scale. But with respect to a given root tone, the average minor   
   tone will be lower than    
   the average major tone. The root tone seems to be an important reference level   
   based on which we experience the frequencies of the other tones of a piece of   
   music.    
      
   Lower frequencies (of sound, electricity, anything) are calmer; higher   
   frequencies are more agitated. That too corresponds with the sad and happy   
   moods. Sad songs also tend to have a slower beat than happy songs.   
      
   With respect to the brain hemispheres, higher frequencies involve more change   
   in a given time interval and correspond to shorter wavelengths, which might   
   support the more differentiating/analytical activity of the left hemisphere.   
   Lower frequencies and    
   the corresponding longer wavelengths would then support the more   
   homogenizing/unifying activity of the right hemisphere.
