| a) Listen to these examples of Ragtime great Scott Joplin and tap your foot to the music. Try to capture the sense that the pulses underneath the music are all of the same duration, and therefore create a flow of even beats. You'll be able to count quickly:
One-two//one-two
One-two//one-two
Etc.
Without getting into theoretical issues here, each “one-two” count equals one beat; therefore every line above equals two beats:

Other examples by another great composer, Jelly Roll Morton:

b)By contrast, although you’ll still be able to tap your foot to the music, you’ll notice in these coming examples that the underlying rhythmic motive is not longer an even set of beats but rather there seems to be a rhythmic cell where the first two beats are long while the third one is shorter.
If you count quickly: One-two-three//one-two-three//one-two (do not pause in the word “two”)
One-two-three//one-two-three//one-two
Etc.
While you listen to the excerpt, you’ll get a better sense of this rhythm. This rhythmic motive has an African origin.
Listen to this excerpt of El Firulete and try to count the pattern above (it is quite fast):

Listen to these examples of Fox Trot and count One-two//one-two to the music:
