Clarín Opus I




The characteristics of the Opus I have been selected because of their stylistic purity and adaptability in terms of location and integration in different musical projects. This model is based on a very common organ built in the 18th century in Castilian small villages. Despite its small size, it has all essential elements of an organ of this style, which makes it perfect for a church as well as an auditorium or lecture hall. These features and its type of construction process give it its traveler spirit. After traveling 5,000 km around Europe and being installed in 9 different locations, this organ is in such enviable good health regarding both its technical and its ornamental aspects.
