Here is the thing with that [as it relates to tattooing]..........
You can have a full, rich, career full of absolutely great tattoos based on technique alone. That is because there is so much great art already out there that you never really HAVE to be an "artist" in a creative way. You can simply use your learned techniques to transfer a specific image from point A to point B and, if the technique is flawless, then even if it lacks "feel" in a sort of way, it will still have that crisp, well polished, professional look, but may never really be THAT tattoo artist that makes you say WTF!!?!??!?!
I have had several apprentices over the years that have become professional tattoo artists. There was definitely a difference in talent when they came to me to learn. Hopefully I taught them the techniques well enough that they can still make a tattoo look good when it is done. A couple I think had an artistic "wow factor" with no techinque at all....and easily advanced through the apprenticeship. A couple didn't quite have that talent so, even though they learned the same techniques, and the work is "good" work, you can tell who started out with more or less talent....even after learning the techniques and theory.
I have found the same thing in the martial arts arena. I outrank my ex wife. I might be the guy who can avoid getting is butt kicked at the bar, but my ex wife, if she keeps it up, will be the one people go take the seminars from as her rank advances. For her, it was always just "natural" in a sort of way. Even from her first class. She is a far better martial artist than I am, even though I have about 7 years of training on her and a couple of ranks.
I am hoping the same can apply to music. . . . . . To where the techniques and understanding can allow someone, who may never be a song "writer" or "creator" to be able to play most things based on the knowledge of their instrument and the understanding of the "why" things sound how they do. If not.........I'm screwed.....lol
