Designed for All Ages, These instruments are a charmingly simple and easy-to-use outdoor instrument that is great for any area, and for children of any age or level of experience. It looks like a xylophone or marimba, but there are no keys and no mallets. Instead, there is a range of tubes with different lengths, which produce a range of notes when a musician slaps them with the palm of their hands.No mallets or paddles are needed! This means that anyone can play, and several children can play them at once. Sound travels through the tubes and shoots out the bottom end with a bright hearty note. The durable materials make it ideal for outdoor conditions. This is a perfect introductory instrument which is perfect for introducing young children to the wonderful creative and cognitive benefits of learning to play music.
