Who cares?
Chord progression or pentatonic scale....who really gives a crap. Music is Music. Me farting could be considered music. I make music using my car's turn blinker and my hands. Anyone can make music. Just like any art form, it is subject to how a person interprets it. You putting a definition to what music is and isn't is just plain stupid.
Approaching music as a "Science" is just ridiculous. How do you explain some of the tribal musicians that existed thousands of years before music was written? Do you think they were like, "Oh chit, we can't play this music because we don't know chord progression or pentatonic scale"?
Music is Music. That's all it is. Like I said before, when you put limitations on an art form it becomes very stagnate and boring. Some of the most famous and influential musicians were able to step outside of what was considered the "proper" way to write and play music.
i give a crap because as someone who has studied and performed music all my life it's sickening to hear these guys call themselves musicians.
The african drummers are muscians because they actually play the drums and use the instrument to express themselves.
Rap music is spoken word to a beat, they don't even try to be in any kind of key.
Music is a science, until you understand that you shouldn't be arguing with me. People have been making music for over a thousand years using the concepts of the ancient greeks (scales and what have you) and it has managed to grow and reinvent itself and not get stagnate.
Yes there is a beat in rap music, but the rapper I'm sure has no clue what rythmic pattern it is (4/4 3/4 etc) so the only actual musical aspect to their "songs" I'm sure they have no clue the science and pattern behind it.
Once again, it's poetry with a beat, its not sung, its spoken. Poets have done this for years and they don't call it music, they call it poetry.
Yes music can be poetry, but not rap because there is no musical skill involved to become a rapper, you just need to know how to use a beat machine and throw together whatever you want without any thought or knowledge of what it is exactly you're doing.
