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:
Edit 2 (2012-Apr-22): I added another
recording that contains these
chords:
F B♭ C F
F B♭ Cmi F
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.

Each of the following two recordings is a sequence of eight C major or C minor chords:
major-minor-1.mp3
major-minor-2.mp3
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
cadences-1.mp3
cadences-2.mp3
Edit: Here’s a listing of the chords in all four sound files.
