Developing inquiry question.

I've been drafting my question many times over the last couple of weeks, not sure what direction I want to go, but I feel I've come up with a question I'm happy with to base my inquiry on as it links my singing teaching work with my early years teaching assistant work. My inquiry question is: 

"What value does the use of music and movement have when, used by teachers, carrying out a learning activity and does this method enhance different aspects of a child's development within early years?"

I would really appreciate any comments and opinions to help with my inquiry.

Thanks
