This is a short piece from my college speakers segment videos. In this one, I go in to the importance about learning music theory. Regardless of what instrument you play, an understanding of theory will give you more opportunities, options and chances at numerous careers in music and having the chance to work in music full time over those that do no have theory well understood.
As a music consultant, I strongly urge everyone in a band to brush up on theory for writing, for creative ideas and for production. You do not have to be Mr. or Mrs. Classically trained, but the better the sense you have of theory, the more options you have to create, produce, react and resonate to the music around you.
No offense to the blogger, but for once I disagree with something he wrote!!! Oops, I said that out loud?
Even “music consultants” can say wrong things sometimes!
When you want to become a musician and become successful in the music industry, it is a choice if you want to learn music theory or not. You don’t need to know the name of the notes, all this, and that. You can just have a really good ear and improvise it all.
There are famous musicians of today that don’t even know shit about music theory. They just have a really good ear. Musicians like Dave Mustaine, Neil Young, Jeff Beck, B.B. King, Jimmy Page, etc. Those guys are really good guitarists. In interviews they have said they don’t know anything about music theory and they just improvise well. Yet, those guys are still able to become guitar legends.
I know some music theory here and there, but I’m no expert at it. You can still get good opportunities in music even if you don’t know music theory. You don’t need to be a professionally trained musician to sound like a pro, just play whatever sounds good to you is all that matters.

You’re misinterpreting what he said. He said you don’t have to be perfectly trained to be in the music business, but it helps to have at least some theory knowledge, and that is 100% correct.
I know that, that’s what I kind of said at the end of this blog post, you don’t need to be professionally trained. I’m just saying it’s a choice you don’t need to learn music theory. It’s all up to you. The point I’m trying to make is that there are plenty of successful musicians out there, who don’t know crap about music theory. They just play everything by ear.
I’m sure they know the names of the notes and the chord names, but they don’t go as far as getting deep into scales and all that stuff.
