Why the combination of music and sign language?
Music also enhances language development, spatial reasoning skills, socialization, and motivation to communicate. Signing is rhythmic as is music, and the combination provides a natural means by which to practice and interact. Both signing and music aid in the ability to keep a steady beat; this skill has been linked to improved reading performance.
