A quarterly journal published by Hermann Scherchen from 1955 to 1966, featuring a Le Corbusier-designed cover from 1957 when it became bilingual (German/English). The publication documented activities at the Electroacoustic Experimental Studio in Gravesano while featuring international contributions in music and sound research. Its scope encompassed acoustics, instrument tuning, recording techniques, sound systems, equipment care, composition, psychoacoustics, and music sociology. The journal included "Gravesaner Blätter Scientific Record," an accompanying series of audio demonstrations featuring experimental sounds and new compositions from the studio.

In 2015, Luca Frei digitised the Gravesaner Blätter to expand its accessibility and created a comprehensive content index. The archive was first exhibited that year in two complementary shows: Hermann Scherchen: Alles Hörbar Machen I at Studio Dabbeni in Lugano (near Gravesano) and Hermann Scherchen: Alles Hörbar Machen II at Galerie Barbara Wien in Berlin (Scherchen's birthplace). In 2017, Frei donated the complete digital collection to Berlin's Akademie der Künste, which houses Scherchen's archive, making it publicly accessible through their online database.
