Harmonies are one of the things that I glom onto in music I hear, that I'm singing. Harmonies and bassline. That's what makes things feel right to me, resonant with my own internal perception of meaningfulness.

*nod* I love J. S. Bach's music - except for his violin solos. :-)

(Partly because they're crafted more for demonstration of technical expertise than for performance, but mostly because they're solos. There's none of the counterpoint and harmony which makes so many of his other pieces exquisite...)
