To some of the posters on here, a definition is handed down from an authoritative source, and should be respected because the the authority of the source is respectable.
With no derogatory implication, this approach can be described as authoritarian.

Darowyn, thank you for putting that in value-neutral terms. It's appreciated, even if I have to say that, in my case at least, it is incorrect. I never heard of 1954 before a few days ago, I don't know who devised it and don't care, and I question authority as a way of life. I like 1954 because it is a useful description of a phenomenon that I have been aware of and involved with for a very long time.

That said, I do know people who take on the mantle of the tradition and can quote every authority to prove how right they are. Every group has its assholes. The only ones who are a real problem to me are the ones who want to tell me what I'm doing wrong while I'm actually playing music. Ugh!
