Re: Uses of dim7

You mean, the "aspirin chord?" So-called because if a composer is stuck in
a key and is getting a headache trying to modulate somewhere else, and since
there are only 3, this is the remedy?

For the purpose of figuring out vectored keyboard layouts, which key
positions within the (12-TET) major and minor scales is it common that
dim7 (made up of 3 minor intervals) is given? For example, in a C major or
minor, would it be common to put in a G Bb Db E or a B D F Ab?
Specifically, in the keyboard layouts I am considering, it is easy to
transpose by merely translating, but the dim7 chord is problematic when
determining the keyboard vertical cutoff, as it lies on four notes
vertically. So I want to have some ideas of its more common uses relative
those common scales. Less common uses, I think is of less importance, as
one cannot cover up that anyway.
