This paper aims at an experimental evaluation of the quality of the wood used in the manufacture of wooden organ pipes. For this purpose we created a stock of pipes, using various types of wood for the walls of the pipes and for the front board. Using this trial stock of pipes, we conducted a series of experimental measurements, proceeding from an analysis of the sound spectrum. It was shown that what exerts the most fundamental influence on the quality of the sound spectrum is the measure of the pipe and its intonation. This reality is confirmed by the fact that despite the use of varying materials and varied thickness of walls, under constant conditions (pressure, temperature) the resonance mode of all the pipes examined is at the same frequency. A further finding is that the material of the front board and walls may have an influence on the creation of a disturbing (humming) component of the tone of the pipe under certain conditions and circumstances, and indeed on the creation of harmonic tones. Even a small change in the original tuning of a historical pipe causes relatively marked changes in the actual sound system of the pipe. This fact has significant consequences in the field of restoring historical organs and on changes to the tuning of those instruments.
