About the method used by his calligraphy teacher and older brother: Johann Christoph Bach. In addition, some observations about how his sons, students and wife dealt with it. Hairs stuck in gum arabic & food stains. Visit my website for more information about Bach and calligraphy: Examples of Bach score calligraphy can be seen on my Instagram account, also suitable for contact via DM: @ BWV 515: “How often does it happen when smoking, if you don’t have the stopper at hand, that you use your finger. Then I think, as I burn myself: Oh, if this hurts so bad, how hot will it be in hell?“
