Including music into learning environments to assist with developing expressive language skills is becoming common. However, there is limited research on the use of melodic-based communication therapy, specifically, to assist in developing expressive vocabulary skills in preschool aged kids. Melodic-based communication therapy is an intervention design to pair music and language in speech therapy, targeting non-verbal and limited verbal children with autism. This investigation set out to determine the effectiveness of Melodic Based Communication Therapy as an intervention for children without autism between the ages of 2-4, with limited expressive vocabulary skills.
