Yantzee by Freenotes Harmony Park.  Heavy duty outdoor musical instrument for parks and schools.
The low notes of the Yantzee create a rich canvas of sound for the other melodic instruments to play over. The individual notes are made with two and a half inch aluminum bars that are resonated by three inch diameter tubes ranging from one foot to two and a half feet long. These low tones have remarkable projection for their size.   Color is Blue
