Cyril Johnston tended to cut heavily into the corner of the shoulder
as this is the most responsive area for flattening the 2nd partial
(Cyril called it the "strike"). Unfortunately, he sometimes made this
area too thin.
At Oakham, he tuned the ring flat of Eb to 609Hz. The tenor cast with
a sharp "strike" and the fact that he left it 2.5Hz. sharp suggests
he was concerned with the shoulder thickness. The original tenor cast
at 22-3-8 (49") and finished at 20-3-6, and the 7th 15-2-19 (43
7/16") and 14-1-3. The new tenor and 7th cast at 27-0-24 (50 7/8")
and 18-3-6 (44 3/4" and finished at 24-2-9 and 16-2-19 respectively.
When I last rang there, the only weight chart to be seen was the
On Pythagorean tuning, I would say that it is not a good system,
mainly because the popular keys such as "C" major have the widest
major 3rds, 6ths and leading notes. That said the intervals are only
slightly worse than E.T. and there are 4 keys that have major 3rds
slightly flat of just (by 2 cents). For all its limitations, 1/4
comma mean-tone gives far better results than either Pythagorean or
E.T. in the 6 good major keys.
