As stated earlier: not this topic again.
Every couple of months someone comes into the forum to boohoo because this or that genre uses simple chord progressions, no musical theory, etc. It was old in the 19th century, it's old now. Popular music is popular regardless if the listener knows what Mode it's written in, what progressions it features, or whether it's major or minor. It's popular because it is catchy, well produced, well mixed, and well received by a majority of people. The very fact that Charlemagne brought up so many different "schools" of thought surrounding classical/orchestral music is the reason that classical is at an all-time decline for listenership: there are simply too many divided factions calling foul against one another and claiming their "method" is better.
As for the comments surrounding knowing and applying theory, yes theory is another tool you can and should strive to have, just as proper sound engineering, from recording to mixing to mastering, is as well, or proper hardware setup, digital sound processing skills, routing, and a myriad of other skills would ALL be great to have for the modern musician and producer. But, remember that most of us are masters of but few of these skills. For those of us who first learned music "by ear", the theory comes later, while production may be easier for us now. Those who were brought up through orchestral playing and theory may not understand proper mixing, equalisation, the application and routing of FX, etc.
If you claim that without theory there is no "good music", then it can equally be argued that without production knowledge the same can be said. Yet, when was the last time you heard someone make the claim that a violinist needs to know how to run a mixing board? It's a silly notion to expect any one person to be a master of all aspects of music. Even composers have their weak points, as many choose to write for specific arrangements, instruments, etc.
Since this thread began with a comment vaguely pointed at the entire Audio Portal and followed with an attack towards Electronic and Techno genres, it's clear that this thread, while producing some great talking points throughout it's pages, was yet another in a long line of threads decrying that Classical (and Jazz, apparently, since that was the last thread of this nature's final ending point) musicians are the only musicians with proper music theory and musicianship.
I'm not trying to devalue the merit of electronic music, nor am I implying that musicians who make electronic music are underneath people with actual musical training.
This comment sums up the beliefs fairly succinctly of those who believe Electronic music is without musicianship: "actual musical training". It is an assumption that Electronic musicians have no musical training and Classical musicians do. The truth is many Electronic musicians (Brian Eno, for instance) have years of musical training, and of those many of them come from "traditional" (Ie. Classical and Modern Orchestral) backgrounds. Electronic music is not some dipolar opposite of Classical music. It is merely another genre, another outlet of music. Within Electronic music are many other sub-genres, some of which ARE more simplistic and less about progressional theory, pacing in the traditional sense, etc. But if you listen with an unbiased ear, you'd note that Pacing, Crescendo, and many other aspects of proper compositional theory are clearly evident in House, Trance, etc., in fact those aspects are some of the most important parts of the music. It is for this reason that the chord progressions may be kept simpler, as the music is built around it's ability to affect a large majority of people at any one time.
The Classical Era's departure from Baroque themes was largely seen in the same light as some Modern classical listeners and musicians see popular musical genres. Classical music was order out of chaos, so to speak, as "Theory" and Structure, harmony with melody and countermelody, took more precedent over Baroque's more layered approach. Many saw the change as detrimental to the health of music. Yet here we are nearly 300 years later with Classical music decrying that change is bad and newer genres are destroying what they worked for, that Theory is all-important. It is important, but every aspect of musicianship is. Every aspect of production is. Every aspect of recording, printing, paper production, logging to produce paper, anti-pollution laws to create viable wood, ad infinitum...
Therein lies the problem: you are not milling your own wood, then pulping it to create the paper your ocmpose on anymore so than I am putting together my own hardware from wire and electronics. We can afford to allow others to do some of the lifting, and that's what these other genres do. They have their own theories, they take the pieces of theory that are most useful to their music, and they use it to it's fullest extent. Just as classical musicians do not spend time understanding the four-on-the-floor drum pattern and how to vary it using other rhythmic patterning and percussion instruments, nor do they know the difference between D'n'B and Trip-hop, how to produce Goa trance using Gamelan timing and tuning, etc. Every genre has it's theories and it's methods. And it's time this was realized and respected by those from other genres.
