Oh my, I love love LOVE this article I read today! Personally, I am always noticing the way various chimes and alerts sound in the world. (ATMs, cash registers, phones, vending machines, etc.) Sometimes they are beautiful and special, other times they are way too loud or too soft. Often it seems like absolutely no thought went into it, which seems like a missed opportunity. The same is true for ambient music in public places, or hold music on the phone. It's great when the music really matches the atmosphere, but not when it's just a boom box in the corner blaring music as a placeholder. Music and sound are powerful forces, and they really impact the way we feel, whether we notice it or not.
