RS 2012 is slightly different from the original Cooper Scale. As Cooper admitted, there was always room for improvement and this has now been done. That said, I am sure there will be corrections in the future, continuing Cooper’s work. The alterations are small, but to those with sensitive ears, they are significant when expressive intonation is employed.
It was a pity that those who criticised RS 2012 did so before trying it. The comments posted here about the new Scale were made before the only prototype was available.
Burkart Flutes have made several flutes to this scale; Stephen Wessel has now started to use this scale on his flutes too.
Flutemakers are welcome to use the figures freely and without acknowledgement, if they wish. The explanation of the Revised Scale 2012 can be seen at http://www.trevorwye.com/cooper1.html and a link at the bottom of that page will take you directly to the figures.
