Prussian Patent No. 19 was granted to Wilhelm Friedrich Wieprecht and Johann Gottfried Moritz (1777–1840) on September 12, 1835 for a “basstuba” in F1. The original Wieprecht and Moritz instrument used five valves of the Berlinerpumpen type that were the forerunners of the modern piston valve. The first tenor tuba was invented in 1838 by Carl Wilhelm Moritz (1810–1855), son of Johann Gottfried Moritz.
Self-portrait (from reflection in tuba), oil painting, 2013. I never gave this a title, but if I did, it would be something like “You have to live with yourself”. Artist’s commentary and musings about self-esteem, self-image and such are after the break.
