Make one variable visible at a time.
Define the question
Replace “improve my writing” with a testable question such as “release pressure earlier at the bottom of the oval.”
Compare examples
Look at several examples and identify exactly which feature changes before starting your own repetition.
Run a short drill
Write a small number of deliberate attempts. Pause between them rather than filling a page automatically.
Record the next adjustment
Write one observation that can guide the next session. This turns practice into a sequence of small experiments.
Why the method stays narrow
A finished calligraphy piece contains many variables at once: pressure, rhythm, scale, material behaviour and composition. When all of them change together it is hard to know why a result improved or deteriorated.
Letterform Diagnostics therefore keeps early sessions deliberately narrow and only combines variables after each one has been observed separately.
Typical session length
Most sessions are designed for approximately 25–40 minutes. Learners can stop when attention drops and revisit the same diagnostic question later.
