I listened on NPR today on my way to work that BMW actually had tryouts for their warning chimes. They wanted one that sounded pleasant, yet serious. Interesting that they didn't say, "Sounds are neutral, so it doesn't matter what we apply." For those who look to the Psalms for direction in church music, I could only find one Psalm that actually described the "character" of the sound with which God desired to be worshipped (I don't consider "loud" to be a character trait). Psalm 92:3.
