Sparkle, this one I can speak to. I started playing the violin at age 4 and had private lessons, as well as in-school Orchestra (as of 4th grade when it became available) through high school. I have not played in any organized way since before having kids (when we were living in Boston just after we got married I played in a chamber music group).
I never did Suzuki, it was always classical violin training.
I hated, hated, hated practicing. It was terrible and I was not allowed to do anything else until I had practiced. Now granted, my parents went overboard and made me practice an hour a day. Once I hit middle and high school though when I had lessons at home once a week plus in-school orchestra and lessons, that eased up.
But, I LOVED being able to play well, loved the orchestra experience, etc. It's a conundrum and very common as far as I can see.
Does she really *get* the relationship of practice to improvement? I'm sure she understands it with climbing. Sometimes with music it can be harder. What I started doing was mentally making every piece into a story in my head, and 'talking' through the music. It sounds silly but it worked for me. When my mom was listening, it was good and fine. When my dad was listening (on practices) it was awful because he was so critical. It can be very isolating, for sure. Are there any other kids who also play nearby who'd get together once a week to practice? Then the other two times aren't so rough.
If she loves music camp, and she generally loves playing but the practicing is hard, I'd say keep at it and let her go at her own pace. She may not progress as quickly without the practicing but if she is getting lessons and playing regularly, she'll at least make small steps.
The other thing that helped me a lot was having the piece I was playing, played on the stereo (dating myself!) while I practiced it. Then I could hear it. I would play with the music, then I would stop laying and listen, then I would play alone, then I would play with the music again. Makes it go faster and it's easier to hear what it should sound like with the other instrumentation.
Just some thoughts, hope it helps.
Now I can use some advice. Ds is enrolled right now in indoor soccer skills practice. He asked to be enrolled, it's through the town, and totally low key and 'fun' (no yelling, no mean coaching, etc.). He claims not to 'like' it although he seems to have a great time while he's there. He needs the activity, and he says he wants to play soccer, but the truth is I think he doesn't so much like the team competitive sports thing. So my question is, do I keep taking him; do I sign him up for little league (which he says he wants to do but never has before, although he loves playing baseball in the yard with buddies), or what? And if not, what do I do with him? He definitely needs an organized athletic activity, more than just running around screaming in the yard. The result of that is he eventually tackles his friends or sisters and pisses everyone off. When he's doing a regular sport activity he still runs around screaming in the yard most afternoons but doesn't seem quite as inclined to mischief.
