He founded the [Corresponding Society of the Musical Sciences] in 1738. Its aim was to enable musical scholars to circulate theoretical papers in order to further musical science by encouraging discussion of the papers via correspondence. Many of the papers appear in the Musikalische Bibliothek. The entry requirements of this society resulted in both the famous 1746/1748 Haussmann portrait of Bach and his Canonic Variations on "Vom Himmel hoch da komm' ich her" for organ, BWV 769.
