harmonic entropy question for Db-G-C

Hello Tuning Group. Can anyone think of anything notable,
psychoacoustically, or in the JI numbers, or in harmonic entropy
concepts, for the chord f-b-e'? (I call it a 'perfect chord' since
the numerator is the perfect number 28, as in 7/5 x 4/3 = 28/15.)

It has an entrancing vibratory which I cannot explain, especially as
the 3rd chord (a sort of octatonic dominant) in the progression a-b-
e', g#-b-e', F-B-E', c-e-b-e'. I could swear that the whole chord
pulses in amplitude (played forcefully on an equal-tuned piano). (It
helps if you stick your head in the piano -- watch the lid--... like
the dog with his head-in-the-gramaphone-logo!)

Does anyone else here this effect? The only thing I can think of,
is, can it be a sort of conceptual discordance between the implied
difference tone/root of low c# (chord c#-e#-b) clashing with the
implied, chord/root, of c major, from the expected resolution of the
tritone f-b?

And what about note e', and the major seventh interval f-e'? I've
always found it interesting that the primary difference tone of the
interval of the major seventh 8-15, is the seventh harmonic, as, for
me, the two types of chords (major seventh and dominant seventh),
have such different, even diametrially opposed characters, to my
ear. So that's another interesting feature of the chord f-b-e',
that it has qualities of both chords.

Or could it be related to an effect Paul once mentioned, where chords
laying higher in the harmonic series (I believe he said, "as long as
the numbers are not too high") have more allusions to multiple roots,
etc, than lower-numbered chords do (eg, 4-5-6).

Thanks, Kelly

So you're tuning it with these precise ratios? I'll need to know, in
order to answer your question.

Equal temperament, then?

You bet it does. Both intervals over the bottom note are beaty ones --
a major seventh and a tritone.

I'm afraid you lost me.

I believe that would certainly come into play for the chord in
question.

Kraig, do you hear this from a piano in 12-equal? Just curious.

OK maybe 16-23- 30 is probably closer which i was going to post. I do hear
the former 'implied' of 'informed by' in 12 ET. Pelog like
It is BTW the generating idea/chord in Stravinsky' Song of the
Nightingale. My favorite Igor piece , even more than the Rite.
