Re: Tetrads
Yo
Interesting! (I love the added 6th.)
Do we need to edit the .k files, or can we download them?
And how can we access these tetrads?

Yahya

But being impatient, I'd hoped for a simple download of the modified
files.
It'll be only a minute's work to edit them, anyway.
Musically, which tetrads most appeal to you? I enjoy using
o the added [major] sixth (e.g. in C, C E G A),
o the major seventh (e.g. C E G B), and
o the suspended [4th added] minor seventh (e.g. C F G Bb).
The latter is especially good in JI, tuned as unison, fourth, fifth,
fourth of
fourth. Two similar kinds of tetrad also use stacked fourths and
fifths:
o three stacked fourths (e.g. C F Bb Eb) and
o the suspended [4th added] major ninth (e.g. C F G D), which
inverts as
o the suspended second (e.g. C D F G).
These all have a more "heritage" feel when tuned in JI (just
intonation),
and add spice to otherwise fairly predictable chord progressions.
They
also simplify voice leading in close four-part harmony. ;-)
