I'm wondering if anyone has a recommendation for a book on traditional calligraphy technique that could be used for self-directed study and practice. I'm a type designer, primarily, so I'm not looking to absolutely master calligraphy per se, but rather develop a working understanding of its basics, the movements of the pen and hand, etc.
I'm not interested in the trendy hand lettering styles that seem to dominate popular calligraphy how-to books. I'd be much more interested in learning to draw blackletter and Old Style roman letterforms (especially roman capitals).
I'm confident that if I were to practice calligraphy for a few months, it would have a positive impact on my digital drawing skills, use of stroke modulation, stress, etc.
