This is weird. It is hard for me to hear the difference in the cadence, but crystal clear otherwise. In the cadence, the problem for me is that the notes are dragging on, like when you press pedal on piano a bit, that makes it hard to discern the difference.
Maybe they lost something in retelling here? Made up new stimuli for which it doesn't work because of harmonics or something?
Or maybe its just me and everyone on this thread? I have a lot of trouble hearing speech through noise (like that of flowing water), i always have to tell others, i am not hearing what you're saying i am washing the dishes. Though i've no idea how well other people can hear something when they are washing the dishes; maybe i care too much not to pretend to listen when i don't hear.
This needs proper study.
The following recordings are played on an acoustic instrument by a human (me), and they have spaces in between the chords. The chord sequences are randomly generated (which means that the major-to-minor ratio is not necessarily 1:1, but all of them do have a mixture of major and minor chords).
Each of the following two recordings is a sequence of eight C major or C minor chords:
Each of the following two recordings is a sequence of eight "cadences" -- groups of four chords that are either
F B♭ C F
or
F B♭ Cminor F
Edit: Here's a listing of the chords in all four sound files.
Edit 2 (2012-Apr-22): I added another recording that contains these chords:
repeated over and over, while the balance between the voices is varied, from "all voices roughly equal" to "only the second voice from the top audible". The second voice from the top is the only one that is different on the C minor chord. My idea is that hearing the changing voice foregrounded from its context like this might make it easier to pick it out when it's not foregrounded.
