AP possessors easily select among that 53 pitch-classes
in an secure way out the 12-tone kernel
consisting in the usually known 12 pitches of:

...without hesitating in labeling the note names correctly
corresponding to the absolute frequencies as reference.

In some AP cases it's also possible
-by some further exercise-
to develop from that initial coarse *12-tone*
upgrading to an 53-tone refinement as goal,
gained stepwise in commatatically
ascending increments,
while the initial *12-tone* base
remains kept as embedded subset:

Real AP posessors should be able to sing by voice
-without any further training- at least
the embedded *12 pitch-classes* within
an accuracy of ~1/3--~1/2 comma
or max. ~0.5--~0.7 % deviation from
the intended exact pitch-frequency,
as indicated in the above list.

Remark:
Sorry, but without that AP aptitude:
There's hardly any chance!
Without that demand it makes imho. no sense to proceed.

The goal:
After he/she has become more (hopefully not less)
secure within that well approved und tested limits,
it's likely that he/she is able to develop the same
skill -by and by- for the other 41=53-12 pitch-classes
inbetween too. After a while AP identification works
for 53 detection as well as for 12 cognotion.

Advice for training:
Listen to old Karajan's a'=445Hz recordings,
but intead of tolerating them in black despair as 5Hz to much
sharp detuned versus the really 440Hz meant,
just consider fully aware that his performances
turn out to be sounding as one comma-class higher
shifted than usually normal:
Learning outcome:
Understand K's ~+5Hz detuning as transposition
of about an whole comma sharper elevated,
as an change in pitchclass about a dozen of 5ths:
Than yours tortured ears acclimate even to bear the skirl Karajan.

Conclusion:
Whenever examine different types of AP possessors,
the usual 12tone-AP should be clearly discerned from
more demanding 53tone-AP refinement.

Quest:
Are here in that group any others 53tone-AP possessors too?
And if so:
Has anybody developed an alternative set of
53 absolute frequencies
as individual preference of personal taste?

Never mind if you are lacking the AP aptitude,
even without that competence it's possible
to improve the cabability of discerning pitches
in the finer microtonal 53-tone graduation,
howsoever independent if you own AP or RP
or even none of them both?
