octave test?

[John M. Formsma]

Dr. Coleman,

Thanks for this information. I noticed that when I tuned the octave they
sounded OK. But I know that an octave must be tested because the ear can
deceive, especially with the octave. I did hear a slight "waver" when tuning
the octave, but the beat was more perceptible when C4-E4-E5 were all played
together. The beat was probably there all along, and my ear/brain will
develop better discernment with practice.

Thanks,

John Formsma

Hi John:

The slow beat comes from the 2:1 and 4:2 relationships of the Octave you
are checking.
