When listening to Haydn one gets the difference. Let us take the Symphony #72 as an example. Listening to this work performed by The Academy of Ancient Music on period instruments and then listening to The Haydn Austro-Hungarian Symphony Orchestra performing the exact same work proves that Rubato does exist in the auditory world. I think the same goes for the nose and taste of excellent whisky. Let us compare Laphroaig, Lagalavulin and Talisker. At first they seem to have a similar nose and taste; but over time one is able to distinguish their differences. Has anyone else experienced this, or am I just floating around in the Chesapeake Bay trying to find Kent Island?
