This study describes a novel system that links an electronic instrument called Cyber Musical Instrument with Score (Cymis) and a game device called Kinect to provide music therapy for children with autism spectrum disorders (ASD). The system was developed to facilitate independent and active participation of children with ASD in music activities and teach them to integrate visual and audio sensory, motor, and physical awareness. The system combining Cymis and Kinect has been applied to both typically developing children and those with ASD, demonstrating that it can be used appropriately by either group. Preliminary studies indicate that the opportunity to "play" a familiar song by making desired movements can motivate children with ASD or similar cognitive symptoms to improve on-task behavior and collaborate effectively with a partner while the accompanying video images can be either motivating or distracting. The data obtained from these trials can be used for further empirical research and practical application of the system in music therapy for children with ASD.

Introduction: Group singing sessions have been observed to result in positive mood changes. One reason for this mood enhancement property is the sense of unity generated by the resulting group cohesion. Based on this sense of unity, the concept of group flow is then likely related to the overall group’s cohesion to a certain degree. However, a question remains surrounding the time changes in the factors of group cohesion and flow during sessions in accordance with the therapist’s expectations. Method: To investigate this, quasi-therapeutic group singing sessions were employed. The present study conducted a time series analysis to examine changes in group cohesion, group flow, and participants’ moods by examining the influence of the song orders that a therapist used for effective mood enhancement. Results: The main findings were that (1) group singing sessions enhanced group cohesion and flow between members; (2) group cohesion and group flow of participants was altered in accordance with the order of the presentation of songs, as per our original expectation. Finally, we found that group singing sessions enhance participants’ positive mood through the resulting changes to the group cohesion and flow. Discussion: These results are applicable for those involved in the organizing of the structures of music therapy sessions, as well as future research into this therapeutic mode.
