The xylorimba (sometimes referred to as xylo-marimba or marimba-xylophone) is a pitched percussion instrument similar to an extended-range xylophone with a range identical to some 5-octave celestas or 5-octave marimbas, though typically an octave higher than the latter. Despite its name, it is not a combination of a xylophone and a marimba; its name has been a source of confusion, as many composers have called for a 'xylorimba', including Alban Berg, Pierre Boulez and Olivier Messiaen, but for parts requiring only a four-octave xylophone. However, Pierre Boulez wrote for two five-octave xylorimbas in .
