Marimba A marimba is a wooden musical instrument that has a number of bars with different lengths that correspond to a different pitch with a different frequency spectrum. The instrument is commercially made from rosewood because the wood is a dense hardwood, although it is very expensive and difficult to cut.

A clean, knot-free portion of a large board must be selected because all of the bars should be made from the same board so that the tone quality and appearance will be uniform. Kayu malam with density of 605 kg/m3 is chosen based on its physical and mechanical aspects, such as decay resistance (the wood is resistant to decay and no pretreatments are involved), dimensional stability, ease of processing, and appearance, which consists of texture, grain pattern, and color.

The Marimba in its simplest form originated among primitive men long ago. It was one of the earliest melodic instruments made by man and references suggest it was widespread throughout Asia and Africa. Though many countries claim it to have originated in their country there is no evidence to prove the exact location of its first arrival.
