I know nothing of music theory and found the article interesting. I have a couple of Yamaha styles called 68Modern and 68SlowRock which do not have the characteristic three beat bass. One style, 6/8 Soul, does have the three beat bass and one style, 6/8Blues, does not. He gives the example of Chicago's Color My World for a 6/8 song. Although I think it sounds fine when I play it with any of these styles, it does sound best with my 6/8 Soul style with the three beat bass.
