Vibraphone

The vibraphone (also known as the vibraharp or simply the vibes) is a musical instrument in the struck idiophone subfamily of the percussion family.
The vibraphone is similar in appearance to the xylophone, marimba and glockenspiel. Each bar is paired with a resonator tube having a motor-driven butterfly valve at its upper end, mounted on a common shaft, which produces 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 shortened; with the pedal down, they will sound for several seconds.
The most common uses of the vibraphone are within jazz music, where it often plays a featured role, and in the wind ensemble, as a standard component of the percussion section.
