The Symphony Light & Motion Mobile stimulates and develops sight and hearing. With four different fascinating movements, it encourages baby to focus on an object and track it with her eyes. The combination of repetitive circular motion and other alternating movements with objects rising and falling and turning around, maintains babys attention and active observation. In addition, the alternating movement of the colorful liquids in the center, with or without the light, enriches the visual experience. The three different classical music tunes stimulate and develop hearing, bringing baby closer to the world of music and developing her musical skills. The combination of music and visual stimuli also develops coordination between these two senses. Fine Motor Skills -The Symphony Light & Motion Mobile contributes to the development of babys eye muscles. Small babies find it difficult to follow objects with their eyes because of their limited vision and weak eye muscles. Consequently, slow-moving objects encourage babies to follow with their eyes thereby contributing to the strengthening of the eye muscles. Cause and effect -The music box has four buttons and can be used as a musical activity center, encouraging your baby to push buttons (cause) in order to receive different musical responses (effect). Language -Listening to music contributes to the development of language in babies. Both music and language consist of a series of sounds that make up sentences. In the first instance, the sentences are musical and in the second, verbal. In both instances, the brain picks up the series of sounds, organizes them and gives them meaning.
