A couple nights ago I was aimlessly surfing the 'net and Google'd "I-vi-IV-V". What returned were dozens of hits about the "50's progression" AKA the "doo wop" progression. That's an understandable nomenclature.
But what amused me is the other name that seems to be popular (although new to me), the "ice cream progression" or "ice cream changes". According to one page I saw the progression is so named because its 'sweet and familiar'.
I found a bunch of interesting trivia about the progression...check it out.
"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
