Abstract

The dimensions and vibrational properties of common reeds (Phragmites australis) were investigated to clarify suitable features for making the vibrating parts of traditional Japanese oboes (hichiriki). To determine its vibrational properties, the hollow cylinder of the reed was split and compressed into flat plates, following a traditional heat-compression method (hishigi). The vibrational properties of reeds selected by musicians were not significantly different from those of the ones not selected, whereas the thickness and diameters of the selected reeds were in a narrow range, between 1.2-1.4 mm and 11.5-12.1 mm, respectively. This suggests that the dimensions of reeds, rather than the vibrational properties, are important factors for making hichiriki. The density dependence of the dynamic Young's modulus of the common reeds was expressed by a mechanical model consisting of bundle fibers and parenchyma cells. Because of low extractives content, the mechanical loss tangent of the common reed was much smaller than that of the giant reed (Arundo donax) which is used for Occidental woodwind instruments.
