Looks like I got a bit hasty. The ladder of 3rds is actually F3-A3, A3-C#4, C#4-F4, F4-A4. Or, if you've been following Bruce Winn's articlels in the past two month's Journal, also including A2-C#3, C#3-F3. Giving a ladder of 6 thirds - I posit that if you achieve a consistant 4:5 ratio for all 6 - your temperatment should be in pretty good shape.

How about if you begin with your A3-A4 octave stretched - i.e. tune A4 to fork, tune A3 to A4, test F3-A3 third vs F3-A4 tenth, with the tenth slightly faster. > > Lurkers - feel free to jump in. > > Carl Root, RPT > Rockville, MD -- Jerry Hunt Dallas, TX
