Volunteering hours

I have a big issue here. I’m very passionate about playing violin, I play in an honors school orchestra and in the state orchestra. I also volunteer as a teacher/ teacher assistant and my local community center. I enjoy it a lot but it very hard, but its very hard work teaching little children. Even more so, its only 1 hour a week and only certain weeks. I enjoy doing it but would colleges view it as a lack of commitment for such a short period of time?
