Conny and Eva made up a plan for their work, and began by going to see workers from the factories that had closed down and the few factories that still existed, as well as representatives of the music dealers that had sold pianos. Arvika, Karlstad, Kristinehamn, Malmö, Linköping, Örebro, Uppsala, Mjölby. Gothenburg, Härnösand and other places were visited as the years went by. Many of the people who at that time told us the stories of their lives are now dead, but their voices live on through recordings. Interviews were conducted, archival documents were saved, photos, brochures, leaflets for the purpose of publicity and tools were copied or collected. .

As work progressed, a documentation centre was developed. When in 1988 the Royal Academy of Music founded its Keyboard Instrument Committee, this documentation centre had a close connection to the work of the committee. After 1993, when the academy re-organized the structure of its committees such that the specialized committees disappeared, some years of free work followed until on 8th April 1998 the present society of the Klaverens Hus was founded.

The founders of Klaverens Hus were almost the same persons as the fellows of the Keyboard Instrument Committee of the Academy of Music which granted a continuation of work that had begun. An important duty is to secure a collection of Swedish-built keyboard instruments, reed organs and self-playing instruments (auto pianos and reed organs) for the future, and to document this part of Swedish industrial, musical and cultural history. These collections give inspiration for exhibitions and instrument research. Important events are concerts and public lectures. Also important are plans for publications, recordings and courses on how to play and treat especially old pianos instruments. The courses are vital to the increased understanding of the individuality of the 19th century instruments. An essential complement to the courses on old pianos is the arrangement of master classes on modern instruments.
