The vibraphone (commonly called 'vibes') is a pitched percussion instrument. It is similar to the marimba, xylophone, or glockenspiel, but it features a motor driven butterfly valve at the end of its resonator tubes, which gives the instrument sound a characteristic tremolo effect. It also has a sustain pedal which serves the same function as the sustain pedal in a piano. The vibes are frequently used in jazz and orchestral music.
