oh jesus. his comment was on the music, many people have said that the power of opera music is such that you don't even have to read the lyrics to get the emotion the power. This is certainly not always true about musical theatre, where the songs and music work together. But as for the music in opera, it is certainly THE most important aspect of the work and the "confidence" (weird word choice, but whatever) of the music certainly can stand alone and do a lot more emotionally than
typical show music. not that there aren't exceptions (ie: most of the greatest musicals written) but the majority of musicals rely on the words and music to work together towards a common emotional goal, where in opera it is different. the music has more "confidence".
