SONOR VB-500

Vibraphones produce a soft, round tone that can sustain for far longer than a xylophone or marimba. They use aluminium bars that resonate for longer than the wooden or synthetic bars found on those other instruments. The vibraphone’s upper bars (accidentals) do not overlap the lower natural bars. Student vibraphones often have bars of identical widths; professional vibraphones have bars of graduated widths, with wider bars for lower notes. These instruments are capable of producing richer tones than student models. Vibraphonists who are accustomed to the richer tones of professional models never want to go back to a student model. For this reason, a serious student might consider a professional model if their budget allows. After all, it’s always cheaper to buy only once.

The vibraphone’s bars can be made with a matte or shiny finish. Shiny surfaces can look impressive, but under stage lighting, they can reflect light back into the performer’s eyes. For this reason, matte bars may be preferred.

Vibraphones also have disks in their resonating tubes that rotate at varying speeds, opening and closing the resonators, resulting in what most vibraphonists term vibrato. Actually, vibrato is a variation in pitch, so this effect should be called tremolo, meaning variations is volume. A small electric motor controls the rotation of the disks and the speed of the rotation can be selected. Some less expensive vibraphones have specific speeds set in steps. More professional units may have stepless motors that allow subtler variations though either type can work well. In the past twenty years or so more advanced computer controlled servomotors allow even greater control of the rotation of the disks. The vibraphone has a pedal that releases a dampening bar (usually covered with felt or similar material) that otherwise will dampen the instrument’s sustain. Like a piano’ sustain pedal, pressing the pedal allows the bars to sustain freely and releasing it dampens the bars. Some gel-filled damper pads are available that can simplify instrument maintenance.
