This Large Marimba is an excellent musical instrument for developing musicians. It has 15 fiberglass keys which produce different carefully tuned notes. This allows kids to produce melodies or even make up their own songs. The mallets which are included with the set can be stored on the side of the instrument so that they don’t get misplaced or stolen. The durable Marimba has a strong framework which is made from recycled plastic. This allows it to remain outside for extended periods of time without sustaining any damage. Bring the gift of music to children with the Large Marimba.
