Terz

Also: Third A "Terz" stop is often constructed as a compound stop, combining ranks of pipes sounding at the interval of a third above the fundamental pitch. The pipes used for the "Third" stop are typically made of metal. They can be of varying lengths and diameters, depending on the desired pitch and tonal quality. The resulting sound of a "Third" stop is typically bright, vibrant, and harmonic in nature. When combined with other stops, the "Third" can contribute to the organ's overall tonal palette, adding richness and color to the sound.
