Since kids are naturally very active and have lots of energy, why not introduce them to musical instruments

Video Touch - Music is a free app for kids and parents, which can help your kid learn musical instruments and develop their brain cells.

The app has many high-definition videos of musical instruments (guitars, pianos, saxophones, etc) where your child can learn the different sounds of these instruments.

It is designed with a simple UI where your child can just tap the instrument and it will play the sound. It has 4 rotating videos for each instrument with popular classical music pieces.
