The intonation and tuning of an organ are key processes that influence the overall quality and final sound of each instrument. Intonation involves adjusting individual pipes to produce the desired tone, dynamics, intensity, and timbre. This creates a balanced and refined sound expression. Organ tuning consists of precisely setting the frequency of the tones to ensure harmony with the rest of the instrument. These processes require great expertise and attention to detail, resulting in a unique and pure organ sound.
