I come from a musical family, my dad used to play the drums, mom was a violinist, sang in a choir and plays the guitar occasionally. I myself am a bassist, can also play (or figure out how to) most guitar-like instruments as well as drums and percussion.
Above mentioned are some points I agree with, mainly musical education being crap at schools. I recall a few attempts to make my class play the recorders, most of which were already broken, without any proper instructions. Now I’m sure there are tortures greater than that, but I’m afraid I won’t ever be able to get that horrible sound out of my head.
As for theory, there were only basics and it didn’t really matter if you understood it or not. So unless you already knew theory from elsewhere, you certainly didn’t get to learn any at school. Maybe things have changed since then, after all it’s been a while, but somehow I doubt it.
Another point I agree with is that it’s hard to motivate children to learn something unless it appeals to them so letting them choose their instrument and focus on genres they like would definitely help a lot.
There’s also this one thing I noticed among young parents I know and that is that they either make their child play an instrument or a sport but rarely ever both. What’s your opinion on that? Personally I think a bit of both would be ideal but that’s just my opinion.
