Dear yahya

As you know , jnd is very personal and is related to physical ,
acoustical , psyco-physiological (training of the hearing system , from
brain to ear !) parameters . wallyesterpaulrus wrote about harmonic and
melodic jnd . my melodic jnd starts very badly at about 2 cent and at 5
cent I have a good pitch discrimination.

But I wonder if your jnd of 2 cent as paul mentioned it as harmonic jnd
, is related to beating and time-interval of each beat ? but if so isn't
it realted to octave :

F1(HZ)........F2(F1+2 CENT)(HZ) ...................NUMBER OF BEAT PER
SECOND..........TIME INTERVAL OF EACH BEAT(SECOND)

50.............50.05779564..........
..........................0.057795643...................................
............17.30234242

100......... 100.1155913.....................................0.115591285

My guide in this matter has been mostly some
discussions I've had with Paul Erlich over the
last few months. I do not remember whether
they were on this list, or in private email. But
I'm sure that Paul, or one of the other list
members, will be able to quote a suitable
reference for this fact.

My own experience tells me that I can readily
discern intervals smaller than 5 cents in slow
music with timbres of moderate complexity.
What does your ear tell you?

Regards,
Yahya
