Close to one million children on the autism spectrum are enrolled in U.S. schools. Geoff Barnes, who works as music therapist for the Campus School at Boston College, has written a book that depicts the emerging relationships and abilities that develop through musical play with children on the autism spectrum. Music Therapy With Preschool Children on the Autism Spectrum (Teachers College Press, 2022) draws upon a research study inside a music therapy group for preschoolers on the spectrum in a U.S. public school. In vivid narratives, readers follow individual preschoolers through their challenges and their steps toward shared attention, interpersonal interaction, and communication during music. Barnes is also an assistant professor at Lesley University.
