Heh, I wish I knew at the time of the discussion that Sondheim had said that; I'm often comparing some operas in class to parts of Sondheim musicals.
It seems when it comes down to it then, my teacher is right. (Place it is in the CD store/building it's performed in=same difference).
But thank you to those of you explaining the conductor vs. the director, that's something I find very interesting.
I actually went to my first ever opera tonight--La Traviata at the Met. What a different, wonderful experience! I couldn't believe that the chandeliers went up (is that actually why they do that in Phantom? B/c that would be a funny coincedence...), how the actors bowed between the acts, how the conductor got to bow with the cast on the stage (awesome!), the focus and reception the orchestra got, etc.
Maybe when it comes down to it, it's ultimately the production that decides whether a piece is a musical or opera, since that seems to be some of the differences--the fact that opera singers aren't miked and the larger orchestra, etc.
Please continue this discussion, it's quite fascinating.
(This isn't why I posted this) but for my final paper, I get to write about Bernstein's score for West Side Story (yaay), considering it to be an operatic score, but when I thought about it, I may just write about the score in general, since there may not be that much in a score that makes it operatic and not musical. Granted, there are certain aspects like motifs that were developed in opera that I can pinpoint, but still...
It's all very interesting. They're really not that different, but they can be treated as such different entities.
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
