musical beats, 4/4 time and syllable stress

http://en.wikipedia.org/wiki/Beat_%28music%29

In music that progresses regularly in 4/4 time, counted as "1 2 3 4, 1 2 3 4...", the first beat of the bar (down-beat) is usually the strongest accent in the melody and the likeliest place for a chord change, the third is the next strongest: these are "on" beats. The second and fourth are weaker - the "off-beats". Subdivisions (like eighth notes) that fall between the pulse beats are even weaker and these, if used frequently in a rhythm, can also make it "off-beat".[7] The effect can be easily simulated by evenly and repeatedly counting to four:

D: Well it lines up with some English words, at least with the 3rd of 4 syllables containing the primary stress.
