Hello Don and List This "Two Octave "A" Temperament" is very similar in concept to my "Quadrant Tuning" principle wherein I set the M3s in descending beat rates starting from A4/F3. F3/C#3. C#3/A3: C#3/G#3, G#3/E3.... etc. There's a useful "cross-check" at C3/G3:C3/F3. Double 8ves in the treble and M10s in the bass are most revealing. It is necessary to learn this routine and mentally "fix" these fast beat rates in the mind in order to fully utilise their worth.
