Conservation of English square pianos from the 1770’s : Common problems and conservation recommendations

In this thesis I explore the preservation problems occurring in English square pianos from 1770. I have investigated three aspects: Which materials do the instruments normally consist of? Which are the common types of damage? What conservation ethics are widely considered among instrument conservators and restorers? With the information from these three questions have I formulated treatment suggestions and general aspects to be aware of when preserving early square pianos. The most important suggestion is not to make any treatment without reflection. It´s also important to be aware of problems regarding storage, humidity, emissions, materials and tuning when preserving an early square piano. I consider these aspects in formulating treatment suggestions to conserve instruments as historical documents and to restore them to playable state. The treatment suggestions can also help and guide conservators without special knowledge of instruments toward better preservation of early square pianos. This thesis aims therefore to improve the care of this fragile cultural heritage
