This may be a slight continuation of another CL rant thread, but I think there's some merit, so starting a new thread.
The Nashville Number System. Can somebody please tell me it's more than just: I chord, ii chord, iii chord, etc... Seriously. There has to be something more, to give it such a grandiose name as "The Nashville Number System". I mean, please tell me there's at least some number to change the key of the bridge or modulate up a half step in the 3rd chorus. Something. Maybe even a number for a secondary dominant, say a major VI chord instead of a minor vi chord. And I won't even rant about adding a 7th to any of those, we'll leave that for another day.
Why is Country music stuck 60 years behind everyone else? And why do they perpetually claim to make inventions of things that were invented 60 years before they "discovered" it.
"We use this advanced music tool called the Nashville Number System. We're so smart. Don't know it? *scoff* You take a chord, and then turn it into a number!!! Then you can use that number in any key you like. We're so smart." --- "Dude, um, we've been doing that in Jazz for like 80 years now" --- "Nuh, uh" --- "Umm, seriously, we learn all songs in 12 keys. Transposition is expected daily" --- "What did you call me?!" --- *facepalm*
You make some points that seem valid today, but not from the time they are focusing on.
Country music, like most folk music is learned by listening and repeating what you hear, it is taught aurally, not visually.
The players most skilful in this form usually do not read as there is not need to, they play together as the music is not of a complicated nature in construction, but it can be skull wise and feel wise.
When sound hit motion picture, and sound started to be recorded the game changed, all of a suffer the need to communicate became important.
Now as musical knowledge does not equate to musical talent and talent does not equate to imagination, then a great singer who happened to write a great song may no nothing of how to explain it to those outside their genre that would expect a score or at least a chart.....maybe the singer does not even read and write.
back in the 20s, 30, 40, etc reading and writing were not skills every one had, so a simple way to communicate to musicians that had the feel and the skills was needed, but not confine them.....so since most people can count, or be taught to count, then numbers is just using a skill they had...the same a stab is using a skill we have.
An interesting point about the early days of movie soundtracks was that all the musicians were orchestral and all could read.
But if you need music that was not classical then you may get the sound, but not the feel...the sound track will sound bland.
the studio system started to mix its musicians, strings and woodwind were mainly orchestral, but brass could be players and orchestral...the blend gave it a freer sound.
Can you imagine a 1930s jazz score being having the feel required if played by orchestral players? On the other hand can you imagine trying to disciple players to record that may not play the same thing twice?
So numbers reflect easily the musical idea of the folk genres, it is about repeating what is played, not analysing it, its function is to put all players on the same page...it understands that classical or formally taught players can always come down to a level. rather than expect those who cannot to go up a level.
