Considering the fact that there is a broad difference between emotional states, notes were specifically chosen across four different octaves as opposed to choosing one octave. The lower tones represented emotions like sadness, shame and despair, the mid range tones which are more sonically pleasing represented emotional states such as, happy, hope, love and the higher end tones whose pitches that tended to be more intense and sharp, represented the emotions that lie in an significantly more agitated state, such as anxiety, hate and anger.
