Before I go on, let’s get one thing straight:
Everyone is capable of playing an instrument at a proficient level with the right support and mindful practice.
Therefore, the first step is the most crucial: picking an instrument that suits your child’s identity and personality, and picking one that they want to play (hopefully for a long time!).
While that sounds like serious business, also remember that students change instruments all the time; this is not exactly “do-or-die” here…yet. Anyone is allowed to change their mind (just not too much).
