Wow, well, how is that any different from what i said 
lol
Anyway, i completly agree with you, and i asked for a teacher at 14, is that too late?
No 14 is not too late
Too late is 16 (at least here)
That means that if you are 16 years old you can't be admitted at the beginner class but need to be examinated (you should prepare an examination repertoire with you teacher) and be admitted at a late begginer-early intermediate class
The point is that children learn faster because they're spontaneous, non-brainwashed, non-conformist human beings ... their bain work trough the alpha stage
That's the brain stage when we learn a lot, we're curious, intelligent, spontanous and don't want to conform to other people and are proud af being what we're are and unique as we are
This stage is usually substituted by the betha stage when we become teen and then adult
The reason is not our brain or phisiological the reason is that we're brainwashed by capitalistic society in being conformistic human beings that act in the same manner and are free from all the fantasy, immagination and sense of awe that they had when they were younger
Even an adult can come back to the alpha state of mind but this require a non-conformist approach to life, and the power to fight against those who want to brainwash his/her and would like to tell him/her how life shouls be lived
That being said how an adult can learn fast as a child is
a matter of how this adult is still a genuine human being instead of a capitalistic society puppet
So that's the reason why many teachers believe that a certain arbitrary age could be a intrance for the piano learning, because they don't know that many teens and adults are able to fight against their brainwashing
In few words, they don't know that amongst a lot of asleep zombies there are people who has awaken
People that are tired of starring in the boring movie of the life that society first stole them and then give gradually to them so that they can believe that this society is giving them something special and that they can also thank for this instead of relizing that those rights were innately of their property
People who want to live their lives instead of starring in it
Anyway, come back to the in topic thread
15 yeard old is considered the age limit when one can start the piano as a complete beginner and still become a concert pianist or a piano teacher
Since at 15 many boys and girls have had already the chance to see and hear a piano they usually know first if they want to play piano or make music ther career
In fact when kids ask piano lessons spontaneously they're usually 9-11 years old
At 16 one is not believe to start piano as a complete beginner but there's no problem is one has already played the piano or studies the piano (also not seriously)
Of course that is what instruction system says but it doesn't mean it's true
Maybe someone can start as a beginner at 50 and become a concert pianist at 65
There are people who were not able to read and write (because of lack of education) at 60 and when they were 80 they had already get two Ph.D and published three books on quantum phisic
What these people (from Russia) had of special was the same state of mind of children, the alpha state, when you're free and really yourself and have no cultural and society limitation, fear, appression and conformistic capitalistic ideas
Meditation can help in this sense
I had my first mediation course when I was 10 years old and it was fantastic
Anyway, no ... 14 is not late
Forcing a child on the other hand to have piano lessons is a crime as he will probably counsciously hate music (without realizing it)
