A portable component marimba comprising a frame having two opposing sections facing each other. A resonator support rack held in place by gravity extends between the two frame sections. A resonator assembly having a linearly arranged series of resonators extends between the two frame sections and is engaged with the resonator support rack by means of two lateral support brackets. A tone bar assembly extends between the two frame sections and includes a linear series of tone bars interconnected by two lateral laces and is supported by a tone bar support rack. The laces may be tied off on cleats located on the crossbeams. The tone bar support rack may include dampening lace support brackets. The resonator assemblies may incorporate balanced resonators. The tone bars may include sustained dampeners.
