Much of my harmonic thinking these days seems to revolve around higher
tensions, and I rarely build a diatonic chord in a composition without
including a ninth and thirteenth (and 11th where appropriate) -
non-diatonic
intervallic structures are another thing, but even then I'm into big
chords
these days.
Generally, having decided my melody and bass notes I'm taking the mode of
the moment, re-arranging it as a stack of thirds to get my 13th chord and
then deciding how to voice it - which includes whether it will be rootless
and whether to include the 5th and 11th.
My question to you guys is simply one of terminology, what is the easiest,
most understandable name for a stack of thirds up to the 13th? Is there an
existing term? Or do we have to invent one, Septachord, perhaps? Urgh,
that
sounds like a disease. A Septad? Like triad, that sounds a bit better.
