摘要： This invention relates to improved percussion musical bars for xylophones, marimbas, bar bells, orchestra bells, vibraphones etc. Traditionally, music played on a marimba, for example, is of one type in the lower octaves denoted by a longer sustained sound, and of a different type in the upper octaves, where a smooth sustained sound is difficult or nearly impossible to maintain due to the rapid decay of the sound emanated from the bars in that range. In this invention, vibraile musical bars made of dissimilar materials, such as wood and metal, wood and rubber, metal and plastic, metal and rubber etc., in the form either a composite or laminations to control the decay period of sounds originating from various bars and to obtain a nearly uniform decay period for all tonal elements in a multi-octave instrument. The proportionate thickness of each dissimilar material in the improved musical bars depends on the shape and cross-section of the bar, the tone-element of concern and the desired decay period.
