We’d like to show the side of the world you don’t normally see on television.
First off, With drums ear protection is an idea. As for learning, there's a balance to be paid attention to. Solid technique and proper body mechanics are very important as the player (of any instrument) can end up doing fine until they want to take it to a more advanced level and then find out some aspect of their playing or the way they hold their body stops them from going further (or leads to injury) and then the "unlearning" and relearning is tough. BUT being too regimented can lead to the student hating the instrument or even hating learning in general and also can force them to be so disciplined that they can't "paint outside the lines" even if they want to. Many great players have moved countless people by playing the "wrong" way, so I think it's vital to work in there a solid foundation but encourage experimentation and for example if the person is learning theory, make sure they know how to ignore what theory tells them they should play. Nothing in music is set in stone. Music is from the soul. There are no wrong souls. There is no bad music....maybe music you or I or someone else doesn't like but if the player likes it...it is good. Make sure that is not forgotten when traveling down the musical paths.
One thing that is a good idea is tie music in with other forms of expression. Join with others. Have the child or whoever start a project with friends, family, schoolmates or by themselves. Get a group going and make something like my music and art for Peace SoundsLikePeace.org project. You (being whoever) could have a section of music one of art, one of poetry, one of a blog thing, it could grow to cover your whole community and more!
Peace to All,
