      Laurence,

      After setting A220 (A3), I set E4 from A3, C#4 from A3 and D4
from A3. Then I set A#3 from D4. Then I set D#4 from A#3 and F4 from A#3.
Then I set C4 from F4 and B3 from E4. This completes my nine-note
temperament.
      I continue on tuning downwards to the tenor break using 3rds,
4ths, 5ths and 6ths as tests for each note.
      Clear as mud? It works like a charm. With the addition of Triads
as tests, it is a very accurate temperament.
