*150 copies limited edition* The organ dates back to 1790 and was made by Venanzo Fedeli, who came from a prestigious family of organ builders. This particular organ is tuned in the ancient way at 430 Hz. Tuning relies on pure thirds that aim to create dissonances within the instrument itself. Since the organ is an instrument modeled according to the principles of nature, the intonation of the pipes was performed according to an incompletely equal system that reflects the natural intonation based on mathematical ratios.

This produces a purer sound for the thirds but slightly harsher and more difficult to listen to. The hardness of the intervals of the organ is a metaphor for the hostile climate that prevails in the Potenza valley during winter and autumn. The sound of the organ with the register of the flute returns a particularly sweet and penetrating sound but, at the same time, a very complex timbre with intricate harmonic texture, given the numerous fluctuations and beats. The warm tones of the organ reflect the good and welcoming sould of the people who inhabit these lands. The absence of dynamics inside the instrument allows the listener to focus and understand the harmonic texture and timbral differences between the various notes more clearly.
