Greetings, I feel like it is impossible to tune a perfect octave without defining where that perfection lies. If the octave is "perfect" at the 2:1 relationship, it is not going to be at the 4:2 and even less so at the 6:3. Perhaps "natural stretch" could be defined a little more technically? Thanks, Ed Foote
