What would take one 'talented' person 1 hour to learn, could take a not so talented person 50 hours. So 50 hours of practice for Charlie parker could add up to a lifetime of practice.
The whole tenor of this thread ( aside from the " you have to have talent" crowd) is strikingly naive.
Have any of you spoken to an MD, and what they had to do to make the grade during the long, expensive, near-ordeal, of becoming an intern, etc?
A person with a 90 IQ is not likely to do this for more than one reason.. just think about it. How would he gain entrance into the schools with such a low IQ? The med students with the 140 IQ's, struggle to make the ordeal of study, and sleep deprivation etc. I wonder if there is such a thing as a 90 IQ Doctor, if there were, would you bring your child or spouse to that Dr?
NOW, the Charlie Parker part is preposterous.... 1 hour for a talent versus 50 hours for a lesser talent, is entirely untrue. I admit my belief in miracles, I suppose nothing is impossible, but that is my idealistic side, not my practical side. You have heard of "God jokes",, I like the idea of God fooling we humans. I sound like an arrogant person here, don't I !
What is missing in this whole thread is the awareness that there is a w-i-d-e hierarchy of musical ability.
One fallaciously diminishes the greatness of the acknowledged great talents of this world by making a mere 1 to 50 of "time spent in practice" ratio. And this is simply untrue.
We are talking about a huge talent versus minimal talent. There is a loooottttt of space between the two. I strongly reject the 10000 hour theory, if it suggests that with 10000 hours of practice a meagerly talented person can transform into a great musician. Never going to happen. 10000 hours will greatly greatly help, but NOT make a genius.
I think this is called dichotomous thinking, or a cognitive dissonance, or a fallacy. With this dichotomy, you have a simplistic polarity eg. the dual ( di chotomy: di means two or dual ) polarities are: "no talent, and talent". So with this model you are comparing just these TWO. But reality ( my experience with musicians, common sense, and innate knowledge of music ) tells me that there is a wide gamut of talents, never just the aforementioned TWO. ( look how awkwardly I am writing this, I do not have a great talent for writing ! But I am not illiterate either. ) Besides, ( controversial opinion warning !! ) music is a deeper more complex subject than math, writing, being a Doctor , or I am referring to the true greats in music. Charlie Parker, Bach, Beethoven are examples of greats in music - again think HIERARCHY as applied to talent, NOT Dichotomy.
And one more nail in this coffin, don't you think plenty of musicians HAVE put the 10000 hours in already? Btw, 10000 hours is 5 hours a day for 5 and a half years.
My personal knowledge of certain famous musicians is they put even more time in than 5 hours daily. Jam sessions were a part of the picture. And you learn at least as quickly ON a bandstand as in the practice room. These stars in music, were constantly playing or writing, not just 5 hours a day.
One last opinion. I know many fine musicians who commit the following fallacy. They are given to stating that there are "many many great musicians". I don't argue with them, but I believe the word great or genius is reserved for a few.
Playing in tune, all the correct notes in the key, scales, chords, with grooving nearly metronomic time, with a big repertoire of memorized melodies and counter melodies, only BEGINS to encompass what greatness in music is. Think Hierarchy, and keep practicing.
