Oh very much so, and I even remember reading a devotional work published before VII that explicitly compared to a mixture of dance routine and a Baroque opera, it has elements of both.    And that is why I always said that while a SHM is a beautiful piece of art, it isn't something that should be daily fare.   And it is very much a show, like sitting in front of a stage watching an opera or dance routine like they used to show on the Ed Sullivan Show.   And though, according to the old rubrics, that was the ideal for the liturgy, what most Catholics got was a ratty old movie theater on the bad side of town, showing nothing but repeats of the  lowest quality silent films....without the fun piano scores or subtitles.
