I think there's currently a tremendous, almost unbelievably large, over-emphasis on music that has a written score in most music programs, which leaves out literally everything that is popular and contemporary. One has to specifically pursue those subjects in elective classes (there are jazz programs that make it up through the 70s as part of the primary coursework, but popular modern music is practically absent from most college music programs). Even when modern music is covered, it tends to be those pieces written by composers using traditional methods, which includes a written score...which is not what is popular.
This is a new phenomenon (though, I guess, studying music in college is also a new phenomenon, when speaking on the time scale of music history). Bach was popular in his time, and he paid attention to other popular composers of his time. What we think of as the "repertoire" that is sort of widely regarded as what someone ought to study as a music major is also pretty new-fangled. There was much less awareness of music from even different parts of the same continent during Bach or Beethoven's time than we have today (I mean, we likely know more about contemporaries of Beethoven from across Europe than he did in his day, and we certainly have better access to history on both sides of his life than he did), and yet we pretend this is how it's always been and that it's the way it should be.
There's a good argument to be made about a common language among musicians...and that historically has been the western repertoire that is generally taught in universities, but there are other common music languages that have similar depth and rigorous analysis (jazz being one of them, perhaps surprisingly, given its origins as popular dance and party music). A music education is supposed to prepare someone to make and/or play music (hopefully music that they like) often with others, and always for others. The musical language they use to speak to those other people doesn't have to be deeply informed by Bach to be valuable.
Of course, if that is the music someone loves and the music someone wants to make, it's great that it's available to them. But, I think it's Eurocentric and extremely limiting when imposed as a requirement.
If you dont like that build a time machine and change history.
I get that someone who loves Tarantino can't sit thru a Peckinpah movie. But imagine if Tarantino had been one of those people.
Bach is to music as Shakespeare is to literature - if you don't nod your head in agreement like a brainwashed zombie when either of these men are stated to be the best in their respective fields, you're automatically dismissed by the crowd of "elitist snobs", for lack of a better redundant phrasing.
I don't side with contemporary works either. The current era (90s+) is so disgustingly cookie-cutter, superficially manufactured by record labels to shovel down our throats in bulk. The 50s through the 80s fared somewhat better; the studios still heavily controlled every aspect of the artists they signed, again following an (as-of-yet unperfected) recipe. At least back then, _some_ of the music managed to weave a story capable of evoking emotion and meaningful thought. I would agree that something has largely been lost over the past century: music no longer being composed, instead being "arranged"(?) to fit specific molds.
tldr; I suppose: a) Fuck record labels; and b) Stop with the "Bach is best" culture.
I don't think you're entirely accurate on why Bach is such a big name when it comes to classical music. It's not because he is viewed as some objective "best" as you seem to be so convinced of.
Western classical music as we know it today didn't really begin until Bach came around (the only exception that comes to mind immediately is Corelli who came a few decades prior). Music historians today recognize that Bach laid out the technical foundations on what Western music is itself. His development of the counterpoint is a major distinction between medieval music and the classical period that followed. As well, his Partitas for Solo Violin and Well Tempered Clavier for Piano have became and remain to this day, foundational parts of learning and improving violin/piano because they train and benchmark almost every technical ability of their instruments (at least in Western music) to such precision. To analogize to programming, it would be like a set of problems that ranged from basic recursion to debugging memory leaks and everything in between and beyond. There are of course other resources such as Kreutzer's etudes for violin but Bach is one of the first and one of the only to do so to such detail. There are numerous of other music elements such as figured bass and dance forms that Bach contributed heavily to, but I think you get my point.
So to summarize, no, I don't think most music historians "nod their head in agreement like a brainwashed zombie". It's not that they hail Bach as some "objective best", it's because they can recognize and respect the formative effects his work had Western Classical music. He is a father of his field much like Turing of Knuth are and that deserves his praise.
Have you actually spent more than 5 seconds looking for music? Contemporary music is the most diverse it's ever been, you just have to look for it.
Even just sorting rateyourmusic by rating will give you an acceptable overview of what's out there.
One meter of Chaconne in D minor has more aesthetic value and beauty than the entirity of Kanyes work. The author is essentially suggesting we just cut out raw organic food and eat processed food all the time
