What is the difference between a marimba and a xylophone?

Answer 1

The Xylophone is most often used in the symphony orchestra and concert band. The bar material is usually wood, preferably Honduras rosewood. The instrument is played with hard rubber or plastic mallets, and has a brilliant, incisive tone. The resonators (if used) are relatively short in length, extending only about halfway down the frame. The instrument sounds one octave higher than written, so the top note on a standard instrument sounds the same as the highest note on the piano.

The Marimba is most often used as a solo instrument or in small ensembles. The bars are made of the same wood used in the xylophone, but they are cut differently, giving a mellow, warm tone that can be almost organ-like in the low register. Mallets are usually covered with yarn or cord. Resonators extend to the bottom of the frame at the lowest point. The instrument sounds where written.

The Vibraphone is most often used in jazz. The bars are made of a metal alloy, usually aluminum. The bars are cut like the mellower marimba rather than the more brilliant xylophone. Mallets are covered in cord or yarn, and are often mushroom-shaped. Resonators extend near the base of the frame at their lowest point, and like the marimba the instrument sounds where written. The vibraphone has two additional distinguishing characteristics: the pedal and the motor. The pedal mechanism works exactly like the sustain pedal on the piano. The motor operates a series of fans (one for every note) that open and close the resonators at various speeds that can be controlled by the performer. These fans and a vibrato to the tone.

Also, the bars on a vibraphone are all leveled at the same height (natural notes & sharps/flats), whereas on a xylophone or marimba, the natural notes are on one level, while the sharp/flat bars are raised.
