i was just wondering and thought that by putting my pen to paper(metaphorically speaking, of course)I might be able to let this question into someone else's head and out of mine: When we are talking about pure musical voices, are they the ones that are raw and unfinished or the ones that are smooth and polished? In science, a pure substance is the rawest and most original sample, but pure water is water that has the impurities removed. Which do we use?
