Due to the lack of music and rhythm courses for children after the epidemic, Kudong Trible has designed an online and offline music interaction education platform for children aged 3 to 8. Through playful educational courses, children can create music together at a distance or offline. By wearing the product in the palm of the hand and legs, it provides light, sound, vibration feedback in different operating modes and adapts to mobile phones, TVs or other monitors. Children can learn three elements of rhythm, note and performance, and achieve age-appropriate musical enlightenment.
