/me puts on muisc teacher hat...
Opera would have an orchestra, not an organ, and voices. An organ is generally associated with church music. Think of the biggest, meanest, most hellish fire-and-brimstone preacher you can imagine... that's a better analogy for the toccata and fugue methinks...
Of course, this toccata and fugue was NOT specifically written as church music, though a lot of Bach's music was (he was a church organist and had to come up with new music every week). He just loved loud organ music I guess.
You're definitely right that it's a good piece of music though. Ah... I remember the Cure concert a few years ago, where their opening music was Barber's Adagio For Strings... how sublime...
Er, whoops, wrong forum...
