Force is a strong word. I don't think we really force our kids to do anything aside from things that will keep them safe (for example- I grab my daughter's hand before crossing a busy road or walking through a busy parking lot).

We definitely have expectations for them regarding their school work and behavior and there are certain "free time" things they are not permitted to do unless they complete their school work, chores etc.

I wouldn't force practicing musical instruments on kids. My son (14) had an electric guitar when he was young and I used to teach him and practice with him but he wasn't really into it and then a few years ago he really got into coding and he wanted to make music for games. We got him a keyboard for Christmas a couple years ago and he has stuck with that. My daughter (6) on the other hand just likes to "rock out" with me. If I play guitar she will grab her ukulele or harmonica or a drum and try to play along. She also has a small keyboard. She loves trying and playing all different instruments wheras my son only wants to play his keyboard now.

And who knows how things change as they grow up. I had a guitar when I was a little kid and mostly I just broke the strings on it but when I was 15 and started playing I became obsessed with it.

Give it time. Let him try out many different things. He has a lot of years to figure out what he likes, doesn't like. I think the best we can do is try to encourage good habits and mindset of always striving to work hard and get better.
