It is not necessarily about the music of the African American soul singer, or the expressively soulful sounds of a blues band. It is about all types of music, for musical sounds are more than mere acoustical organisations and presentational structures. Music is a voice that both expresses and engages the human soul in profound and powerful ways. Music is a voice of the soul. We have all experienced this ineffable quality in music that speaks deeply to the human heart in powerful tones.
Music contains harmony and dissonance.
Music pleases and disturbs. Music builds tension and releases it, thereby providing sensation of pain and at the same time pleasure. Music is both ecstatic and tragic, frenzied and calm. Music brings laughter and tears. Music embellishes the noble and flirts boldly with the perverse.
