  Work Details  
  Companion instrument to the diamond marimba, the quadrangularis reversum is a marimba that has a diamond-shaped center that it is the exact mirror (reverse) of the diamond marimba. On either side of the diamond are flanks of extra bars in an alto range. All bars are resonated by hanging pieces of bamboo and the entire instrument is contained in a eucalyptus branch and redwood structure that is certainly one of Partchs greatest musical instrument sculptures. The quadrangularis reversum was used by Partch in only his two last pieces.
