 note = {This paper presents a research about the making musical instruments with prestressing steel wire and ultra high strength reinforced concrete (UFRC). The strings, the harp, was made by using the UFRC to thin the material’s thinness of the sound box and prestressing steel wires were used as strings. From the results of this research, it was possible to increase in the natural frequencies of the sound box by making concrete board using the UFRC. Moreover, when prestressing steel wires were applied as strings those were suitable to use thinner wires to consider to tones. It can be expected that corresponding to various sounds by obtaining natural frequencies of the material that matches the materials to the frequency of the any sound in the future.},
