Who invents the music definitions like metal, rock, house, hard rock and so on, and...?

How they arrive to a consensus in a world scale for those definitions.


Would Black Sabbath and Led zeppelin be considered today as metal?


There was no metal when they first appeared.


Does the concept (like death or satanic) give the music its definition, or, is it the way is sounds?


If you know a new definition which is not yet widely known, please share here.Who invents the music definitions like metal, rock, house, hard rock and so on, and...?
radio DJs? i know rock n roll came from it that way. generally its from music reviewers when describing the sound and it just sticks if it sounds right. also, some fans might describe a new sound of music like death or thrash metal and it sticks as it gets thrown about and used lots by fans through fan talk. melodic death metal is not widely known, it uses a melody and structure and is very catchy. this kind of metal mainly comes from the netherlands, sweden, norway etc. the best band to hear to know what this sub genre of music is are 'kalmah'Who invents the music definitions like metal, rock, house, hard rock and so on, and...?
I think that genres like rock, meant it was hard, and heavy at the time. When rock first came out, it was the heaviest thing out there. Then metal was made, and ';metal'; is harder than ';rock,'; so I guess they decided to name it like that.





When it comes to subgenres, I think it depends on the lyrical content whether it's ';satanic'; metal. the subgenre deathmetal is named after the way it sounds, and I guess the lyrics contribute, because death metal usually sings about death. But when it comes to genres like punk, that's also contributed by it's lyrics, because punks are anarchy, rebel type people and punk's lyrics usually talk about anarchy and doing whatever you want.





I guess it's kind of both, because there are genres like hardcore which are based entirely off the musical influences it has.
It comes form different places really, which is only amplified by the fact different people have different names for things. Especially the term ';rock'n'roll';, which was originally used for 'rockabilly', but as since been given to virtually all genres of rock, and even some brands of metal.





However, certain words like ';satanic'; are applied for it's connections to Satanism, while ';psychedelic'; is applied due to their association with Entheogens.





So really, it's up to the listener. Although magazines, the fans and the bands themselves will often create or modify terms, most music has a number of cross overs anyway.





A new one I'd say, would be Dub-step, which to me, sounds like Hardstyle. However it's quickly growing into it's own genera.

S.
some are made up by record execs, radio dj's, the bands themselves, fans, and yeah, pretty much it depends on the genre, black metal is what the bands of that style called themselves, naming themselves after the Venom album ';black metal'; however Nu Metal is a term that was created entirely by the record companies to try and market any band that sounded even remotely like Korn.





death as a topic kind of gives death metal it's definition, but only so far as the bands of that style that came out in the early 90's mostly sang about death, now it can be about anything, same with black metal, the word black was chosen because black=evil=satanic, so yes most black metal bands in the early 90's were satanic, and now, even though a lot of it is satanic, it's not a requirement, black metal can be about anything.
