The Xylophone in Greek translation means "wooden sound". It is made from bars of wood producing pitch from the scale when struck with a mallet. They range from 2 1/2 octaves to 4 octaves and are set up in the same way as a piano.
Modern western xylophone are made from rosewood, padak, or synthetic materials such as fiberglass. Mallets are made from anything from very hard rubber or acrylic to yarn depending on the type of sound.
