I think back to my early school days and remember the girl or boy in my class who could draw and paint better than the rest, without any tuition. In my opinion, they posses a natural talent for art. I believe that some children are more gifted than others, and consequently are easier to teach and are more likely to achieve higher standards faster. Without deterring pupils from learning a brass instrument, the teacher should also outline the level of commitment they expect from their pupils. They should also remember to tell them how much fun playing a musical instrument is.
Many parents try to live their lives through their children.
My experience is that this situation rarely lasts. It can also be useful to ascertain whether a child can form an embouchure and can buzz, and to assess the level of intellect of a child. This result should not however, prohibit the enthusiastic and less able pupil from learning to play. Choosing an instrument. Ask the pupil what instrument they would like to play.
