A type of xylophone that was created in the early 20th century. It was basically a xylophone with the range extended downwards to include those pitches normally in the range of the marimba. This instrument is not a mix of the xylophone and the marimba, it is a xylophone with an extended range. The xylorimba has a range of four octaves (c to c4). It sounds one octaves higher than the written note.
