Steinhausen studied for years the movements of the violinists' shoulder and arm, also on the basis of his practice as an amateur of the instrument. In 1903 he published the fruit of his research in a book published in Leipzig: Die Physiologie der Bogenführung auf den Streich-Instrumenten (Physiology of the conduct of the bow on stringed instruments). Already in this study there are references to piano technique, to which he dedicated a specific and fundamental treatment in the volume Über die physiologischen Fehler und die Umgestaltung der Klaviertechnik (On Physiological Errors and the Transformation of Piano Technique), also published in Leipzig in 1905.[citation needed]
