You're committing the classic fallacy of not breaking things down far enough:tapper mike wrote:There is a whole history of jazz showing it's evolution into popular music.
A G7b13 chord derives from a G7 chord with a few extra notes in.
ABAA form comes from ABA form with a repetition.
The ii-V-I progression goes back to the very first pieces of tonal music, around the turn of the 17th century.
None of these things are uncommon in pre-20th century music, and in all cases, the basic underlying theories had been in place for hundreds of years. Jazz musicians expanded on them of course (based on other influences), and went off in their own direction, but the basic building blocks are the same.
And you think this description doesn't apply to classical musicians too?tapper mike wrote:Popular music developed from musically itinerant individuals who had little to no formal classical training. They put things together which sounded good based on the limited information they had. A lot of conventions of popular music were not derived from great mathematical computations instead they used "it sounds good to me lets run with it"
It pains me sometimes to see how deeply some people misunderstand "classical" music. They view it as rigid, formal and simplistic - or, in your words "derived from great mathematical computations" (nonsense by the way). You fail to understand that "classical" musicians have been improvising over a chord sequence and so on for hundreds of years.
But if you really wanted to learn music theory, you'd be much better off finding some classes, getting a teacher, and reading a professional book or two.stillshaded wrote:I'm just going to say that you can use musictheory.net to learn all the basics, then you could try to learn one new concept a week or something via wikipedia + cross-referencing.
