Octave Stretch in other Lands

[Clyde Hollinger]

Friends:

I used to teach music theory on a very elementary level, so I don't
remember ever talking about 15ths, but I'm inclined to believe it is a
double octave.  Consider the following, based on the C scale:

   C    D   E   F   G   A   B    C     D   E    F    G    A    B    C
unison 2nd 3rd 4th 5th 6th 7th octave 9th 10th 11th 12th 13th 14th 15th
