I don't know about your particular child, however-- some seem to respond very positively to classical music, including 'calming' Chinese music.
I have this cd and have used it with my preschoolers:

I also like quieter classical music for youngsters, and more mellow jazz. I think you might need to do some exploring. Prokofiev's "Peter and the Wolf" is wonderful for kids to listen to while doing playdough or other sit-down activities and encourages listening.
