Vibraphones

While both are mallet percussion instruments, a vibraphone uses aluminum bars that resonate with a sustain pedal and motorized vibrato arm, while a marimba features rosewood bars and a drier, more focused tone.

Faster motor speeds create a wider, more pronounced vibrato effect, while slower speeds produce a subtle shimmer. The ideal speed depends on the desired musical expression.

Heavier bars generally produce a darker, more resonant tone with longer sustain, while lighter bars offer a brighter, more articulate sound.
