In what sense do you mean that? I certainly don’t think that the most creative writers are the ones with the most limited vocabularies and I don’t think the most creative musicians are the ones with the least technical ability with which to express themselves.
The most glaring example I can think of which proves that statement wrong is: The musicians with the least talent are not the most creative. I’m using the word talent in the sense of being born with the ability to become great at something. That doesn’t mean dedication and practice aren’t required; it means that with dedication and practice, their God given talent allows them to reach levels of greatness which the average person could never achieve no matter how hard they worked at it.
In sports, talent and genetic potential are often used synonymously. if two baseball players both realize their genetic potentials, the one with the greater genetic potential, or “talent” will be the better of the two. Nobody with an average of God given talent or an average amount of genetic potential will ever be able to hit a baseball as well as Ted Williams or Babe Ruth could. Ted Williams worked relentlessly to achieve his goal of becoming the best hitter that ever lived. In 1941 he batted .406 for the season and to this day, 77 years later, no baseball player has ever hit .400 or above for a season average. He studied the art of hitting a baseball. ted Williams wrote “The Science Of Hitting” which many players read and still read as if it were the bible of hitting. In that book he approached learning and explaining the art and the science of hitting in a similar way to how you, @Troy, have approached “cracking the code” of picking. Despite his incredible natural ability, Williams, unlike most “naturals” could tell you exactly how he did what he did. Babe Ruth, a hitter with probably greater talent or natural ability than Ted Williams probably couldn’t have told anyone how he hit a baseball the way he did. It was just a gift.
Ted Williams had tremendous gifts too, such as incredible eyesight. he could read the label on a record while it was playing. Despite his natural gifts or talents, he relentlessly pursued studying the science of hitting a baseball which he claimed was the single most difficult thing to do in sports, citing the fact that if a player gets 3 hits out of ten times at bat on average, he’s considered an excellent hitter. A basketball player who sinks only 3 out of 10 baskets attempted or a quarterback who completes only 3 out of every ten passes attempted would be fired.
My point in bringing up baseball in comparison is to bring up something where excellence can easily be defined by several obvious and objective criteria. Music can be judged by objective criteria as well, since anything which exists i reality can be judged by objective criteria, but only to a certain extent. There are many qualities of music which are subjective in nature, yet just like baseball, excellence (which includes the ability to be creative in songwriting and improvisation) is attainable only to those who along with dedication and practice, have great talent or natural ability. The most creative musicians are the ones with the least limitations imposed upon them by their level of natural ability or genetic potential. Having greater God given talent and having greater technical skill allow for greater ability to create; in fact their creativity is only limited by their level of their talent to come up with ideas and the technical facility with which to execute those ideas whether that means having the vocal range to hit the notes required by their creative ideas, or having the necessary level of picking technique to execute a rapid, complex passage of notes a guitarist is inspired to play in an improvised solo.
