Three tree ring sequences were collected on the soundboard of the Stradivari harp. Due to the presence of the strings in the centre of the harp soundboard, the sampling of the tree ring widths was focused separately on the right side (RX), the central (CX) and the left side (LX). Tree ring measurements were carried out by using the Video Time Table (VTT), an instrument that combines a portable measuring device and a digital, high-resolution video camera. The VTT allowed non-invasive measurements of the tree rings to be made in situ and to immediately verify the quality of the sampling. The growth rings of the central portion were sampled using a high-resolution camera, which made it possible to bypass the barrier formed by the neck and strings. The consequent parallax and focus problems were overcome by taking many photographs from different angles. The measurements on the photographs were made with the CooRecorder program. The dendrochronological data were acquired with the PAST4 program and graphically processed and analysed with the PAST4 and 5 programs.
在斯特拉迪瓦里竖琴的共鸣板上采集了三个树木年轮序列。由于竖琴共鸣板中央有琴弦，树木年轮宽度的采样分别集中在右侧（RX）、中央（CX）和左侧（LX）。树木年轮测量使用了视频时间表（VTT），这是一种结合了便携式测量设备和数字高分辨率摄像机的仪器。VTT允许在原地对树木年轮进行非侵入性测量，并立即验证采样质量。中央部分的年轮使用高分辨率相机进行采样，这使得可以绕过由琴颈和琴弦形成的障碍。通过从不同角度拍摄许多照片，克服了随之而来的视差和对焦问题。照片上的测量使用CooRecorder程序进行。树木年代学数据通过PAST4程序获取，并使用PAST4和5程序进行图形处理和分析。
