Why you've never really heard the 'Moonlight Sonata'. This intrigued me because I played "Moonlight Sonata" at my very last piano recital and believe you me, I heard it a lot that year. I may have even had a professional tape recording of it for inspiration (yes, this was in the days BEFORE CD players). So I found this article intriguing but especially cool are the sound files that showcase the difference between modern pianos and those from the classical/romantic eras; that sound is distinctly different. I'm ashamed to admit that I prefer the more modern sounding pianos, but it could also be that's what happens when you spend six months with a piece of music.
