In the frame of the CO.B.RA project, funded by the Lazio Regional Authority, ENEA carried out a series of diagnostic investigations on numerous instruments from the rich collection of the National Museum of Musical Instruments of Rome. This paper presents the results related to the study of the conservation status of one of the rarest and most significant museum’s instruments, the Barberini harp. To study the original wood essence, the decorative apparatus, the integrity of the instrument structure and to assess its conservation status, two types of diagnostic techniques were used: X-ray radiography and observation of micro-samples under scanning electron microscopy (SEM). Both the analysis methods performed enlighten the realisation techniques and materials of the Barberini harp as well as its state of conservation. The data collected from the diagnostic investigations, in particular those on the wood essence, will be useful for the building of modern instruments, having identical structural characteristics to the old ones, which could be played without the conservative problems connected to the handling of an instrument hundreds of years old, obtaining at the same time the same kind of sound.

巴贝里尼竖琴的诊断调查

在由拉齐奥地区管理局资助的CO.B.RA项目框架中，ENEA对来自罗马国家乐器博物馆的丰富收藏品中的众多乐器进行了一系列诊断研究。本文介绍了与研究最稀有和最重要的博物馆工具之一的巴贝里尼竖琴的保护状况有关的结果。为了研究原始的木材香精，装饰装置，仪器结构的完整性并评估其保存状态，使用了两种诊断技术：X射线射线照相和在扫描电子显微镜（SEM）下观察微样品。两种分析方法都对巴贝里尼竖琴的实现技术和材料以及其保存状态起到了启发作用。
