Description: vibraphone , vibes , showing pedal bar , a percussion instrument struck with mallets . Similar in appearance to the xylophone and marimba , the vibraphone uses aluminum bars instead of wood . Each bar is paired with a resonator tube having a motor driven butterfly valve at its upper end , mounted on a common shaft , to produce a tremolo or vibrato effect while spinning . The vibraphone also has a sustain pedal similar to that used on a piano : When the pedal is up , the bars are all damped and the sound of each bar is quite short , with the pedal down , they will sound for several seconds . Frequently used in jazz music , and used here in the modern symphony orchestra by harrison birtwistle , in his Mask of Orpheus ( for the BBC Proms 2009 ) .
