Is marimba a keyboard

Marimba, xylophones, vibraphones, and other mallet percussion instruments are often referred to as "keyboards". However, in reality, a marimba is NOT the same thing as an electronic piano (keyboard)...or a computer keyboard for that matter! Mallet percussion instruments are called "keyboards" since they are set up similar to a piano. They have the same standard "white keys" and "black keys" (naturals and accidentals) as keyboards have. Furthermore, marimba music is often written on the grand staff (both treble and bass clef) and is played with four mallets.
