A no-stretch tuning has each note tuned to exactly double the frequency of the note one octave below it. When you tune 2:1 single octaves beatless you do get some stretch because the second partial of the lower note is more than double the fundamental. Of course you get more stretch when you use the 4:2 partials (the 4th partial of the lower note and the 2nd partial of the upper note). I suspect that if the 2:1 octave is tuned beatless then the double octaves will sound flat. -Robert Scott Ypsilanti, Michigan
