What's all this discussion of "Nth rate" about? Popularity? Greatness? Is it objective?
It's a highly subjective phrase. When you call a composer, or work,
"First Rate", it means you think everyone thinks it's great, even 'major'.
When you use
2nd rate to describe a composer, or work (or a film, or an actor), then you're simply saying it's not 'great' nor 'major'. It may certainly still be 'good', just not as 'good' as a
1st rate composer.
For instance, in comparing works of
Beethoven with each other, one might say that his
9th, 5th, and
3rd Symphonies are
First Rate, while his
2nd Symphony is
2nd rate in comparison.
One could take it further, by claiming that his
Wellington's Victory is
3rd Rate.
This 'rating system" is comparable to the rating system for film actors, in which an "A-List" actor like Johnny Depp, Tom Cruise, and Tom Hanks make millions of dollars per film, while B-List actors like Amber Heard or John C. Reilly only make tens of thousands of dollars per film.
