Wood from several tropical trees of the genus Dalbergia, all having a dark red or purplish color streaked and variegated with black. Rosewood timber produces a rose-like smell when cut. The wood has a fine grain, smooth texture, and polishes to a high gloss, but because of its resinous nature is difficult to work. It is used for cabinets, musical instruments, piano cases, and veneer. It was popular during the late 18th and early 19th centuries. It is still used to fashion xylophone bars, but waning supplies restrict its use. Only around 15 of the species in the large genus Dalbergia yield rosewood.
