(sometimes known as the xylo-marimba
) is a pitched percussion musical instrument
which is a sort of combination of the xylophone
and the marimba
. Like them, it consists of a series of wooden bars laid out like a piano keyboard
, and it combines the range of the two, usually spanning five octaves from the C two octaves below middle C
to the C three octaves above middle C. Its music is written in both the treble and bass clefs.
The instrument has been used in a number of 20th century classical works, including Alban Berg's Three Orchestral Pieces (1915, revised 1929), Pierre Boulez' Le marteau sans maître (1955) and works by Olivier Messiaen.
