Mozart: The Marriage of Figaro (Le Nozze di Figaro) in Full Score
Nobody could make voices and instruments work so perfectly together as Mozart, and it's fascinating to read through a full orchestral score to see how he did it. Like all of Dover's scores, this one is a reprint of another publishing house's work. This particular house, C.F. Peters of Leipzig, gives the text in the original Italian -- and in a German translation from 1941 that's still sung in Germany and Austria today.
