Temperament selection

[John Dutton]

Jason's website is a great reference.  He also has a pdf version of the
website (or used to anyway) for those that like the tactile sensation of
reading paper.

Attaching thumbnails of  Vallotti, Young, Vallotti-Young, Moore, Broadwood
Best, Coleman 10, and Coleman 11.

 

Using the frame of reference of ET major thirds as 13.7 cents expanded:

 

To arrange them from "closest to ET" to most extreme, the sequence would be:

Coleman 10, (thirds ranging from 10.7 to 15.7 cents)

Moore (9.7 to 15.7)

Coleman 11 (7.7 to 17.7)

Broadwood Best (6.7 to 17.7)

===

The Vallotti-Young group all have very similar extent of extremes, all
reaching 21.5 cents, which is the largest "acceptable" major third in any
well temperament.

Young has a single most-contracted major third (C, 5.4 cents) and a single
most-expanded major third (F#, 21.5 cents) and smoothly changes the sizes of
the thirds around the circle of fifths; both the Vallotti and the
Vallotti-Young have three equal smallest thirds ( 5.9) and three equal
largest thirds (21.5), and adjust the intermediate thirds smoothly but in
slightly larger steps than the Vallotti.

There are many WTs in between these two groups.

That might be a little strong for some, try Moore & Co.(Representative
Victorian)

or Broadwood's Best. Both mild Victorian WT's.
