John Gunn's tutor The Art of Playing the German-Flute on New Principles, released 20 years after Luke Heron's A Treatise on the German Flute, stands as the most comprehensive flute tutor to emerge in England during the eighteenth century and is among the most significant in Europe for that era. Its meticulous approach to flute playing makes it an invaluable bridge from the eighteenth to the nineteenth century. Originally published in London: Sold by the Author, 1792. English. Contains 31 pages of text and 53 pages of music for one-keyed and/or four-keyed flutes. With an updated setting of the text and scholarly introduction by Janice Dockendorff Boland, 2024.
