That is one world if you're comparing the music to the picture. Alternately, you can listen to the music like this, signified by this graphic diagram,
The other two worlds are signified by the higher notes alternating with the low notes. Listen to the example again so that you understand clearly what we are discussing here. Listen to the music progress from note to note, as opposed to hearing the high notes as one melody and the low notes as another. Listen again!
Do you hear it? In case you don't, relax and just keep listening until it makes sense. This is part of what it means to perceive polyphony and counterpoint.
Here is another example of the three worlds concept with three distinct parts. It begins with one beat per note with three beats per measure. Notice how there is a low part which moves along at a slower pace than the upper parts which you can hear on the 2 and 3 beats of each bar. These notes are played by plucked strings and low winds. Then insert the solo violin line on top and once again you have 3 different lines moving at the same time. Listen!
That's a portion of the second movement from Violin Concerto No. 2 by Prokofiev.
Doria by Douglas Leedy was from a 3LP set known as Entropical Paradise, released on the Seraphim label. It is probably gone from the catalog.
