I rather agree with above answer the younger the better. How about checking up on when the greatest musician of all time starting learning. I refer to Wolfgang Amadeus Mozart.
He was taught to play various music instruments by his father Leopold Mozart even before 1761 when he was just four. He started composing music at the age of 5 and composed some wonderful music for the violin and equally wonderful compositions featuring almost all the other instruments of the orchestra. He became a superb performer on the klavier and the violin up to his death in 1791 at the age of just 35.So in comparison with Mozart perhaps your daughter is starting just a bit late at such an elderly age of six.
My opinion is to get kids involved in musical instruments at an early age. I think 6 years old is a perfect age to begin taking lessons. Kids are learning and their brains are like sponges.
Let them learn as much as they can right now. Who knows, maybe in 5 years she will be an amazing violin player!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
