The Symphony-in-Motion™ stimulates baby's sense of sight and hearing with classical music by Bach, Mozart and Beethoven. Through its four movements, the mobile draws baby's attention, inviting her to actively gaze and follow it as it moves. Three carefully chosen classical music selections, each one different from the other and played repeatedly, develop baby's sense of hearing, and draw her closer to the world of music. The integration of auditory and visual stimulation helps develop coordination between these senses as well.

The mobile contributes to the development of the eye muscles. Because of their weak eye and neck muscles, it is difficult for newborn babies to follow or track objects. The mobile's slow, smooth movements draw baby to follow them, helping to develop and strengthen these muscles.

The moving objects that disappear and reappear from baby's field of vision, at fixed intervals, contribute to internalizing the concept of object permanence.

The integration of music and movement helps calm baby, as she learns ways of calming herself.
