Variability of macrostructural parameters in resonant spruce wood (Picea abies L.). This paper presents the results of research on variation of annual rings width and percentage of latewood in the resonant spruce wood. These parameters of element intended for building musical instruments shall be adopted as the main criteria for visual assessment of resonant wood quality. The results of the study indicate that the mean values of these features do not fully reflect the degree of heterogeneity of cyclic macrostructure of wood. They should be complemented by the results of statistical analysis (variance) indicating the level of significance of differences in macrostructural parameters in individual increments of elements visually classified as resonant wood.
