| DIAMOND MARIMBA | |
| BUILT: | 1946, at Madison, Wisconsin. |
| SIZE: | 40 inches high at the back, 33 at the front, 36 inches across the top. |
| MATERIALS: | The blocks are Brazilian rosewood and Pernambuco, mounted on thin foam rubber; the resonators are Brazilian bamboo. |
| TONES: | The 36 blocks are arranged in diagonal rows, so that one sweep of the mallet will sound an arpeggio-like chord. Strokes with the right hand are major; those with the left hand are minor (from top to bottom). The range is almost three octaves, beginning with the approximate C# above middle C. |
