In 1885, the scientist Ellis analyzed the work of seven tuners.
These charts represent three of them.
Comparing these Victorian-era tunings to the earlier Well temperaments,
we can see that the differences between the "smoothest" and "harshest" major thirds have been reduced.
Broadwood's Best: This tuning was done by one of Broadwood's "best tuners".
A shade less color contrast than the Broadwood Usual.
Broadwood's Usual: This was done by Ellis's personal piano tuner, a "usual tuner" from Broadwood.
A shade more color contrast than the Broadwood Best.
Moore (sometimes called "Representative
Victorian"): This tuning was done on a harmonium
by a tuner from Moore & Moore. Note that there is some key-coloring but
no M3 is expanded beyond 16 cents.
