Since I've been doing music theory with my
broken wing, I was asking my teach
about how to easily identify tritones in
standard notation. For major keys, he said
there is only one between the 4th and 7th
(excluding notes with accidentals).
So then it must follow that in the relative
[natural] minor, you'd find them at 6 and 9/2.
This is because the same two notes are involved,
axcept that A becomes root (#1) in Am.
IOW, in C/Am the diabolicus notes are F and B.
Interestingly, it doesn't matter if it is 6-9
or 2-6 (they are equal sized intervals). That
also means 4-7 or 7-4 are likewise the same in
Have I got this right?
If so, it makes identifying these easier in
Obviously, things are trickier for other
minor scale forms.
