This is a question about the ability to perceive irregularity in
rhythm. It comes from Boogie Bob, Lansing's foremost rhythm and blues
What is the JND for perceiving an unequal division of a beat into
A quarter note beat could be divided into two eighth notes.
Theoretically, that would be a 50-50 division.
It could be divided into a dotted quarter and a sixteenth.
That would be a 75-25 division, clearly different from 50-50.
Can you distinguish between 75-25 and 67-33? How about 75-25
Presumably the answer depends somehow on the tempo. How?
Because this is a question about rhythm and not about the perception of tone
duration, there needs to be a context. Probably it's best to think of a
regular and indefinite repetition of the two-note sequence in question.
That establishes the tempo and context.
Anybody out there with information on this subject?
Next: how about the ability to reliably PRODUCE such a division?
