m14th test

[David Renaud]

I've recently "discovered" the test.

    A friend(technician) told me to match
the 14th to the major third one tone above the
top note. i.e.: E1-D3 to E4-G#4 so the beat rates
are the same.
     This gives the root, third, seventh,
of a nice open dominant cord voicing. When the
upper and lower beat rates of this cord match
I like the effect. I find this more clear then other
tests in the bottom. Tenths give me less stretch
then I like in the bottom, so I now find 14ths check a
closer reference.
