If Beatles wrote songs with ARIS I believe soon they would discover patterns and thus created thousands more hits we all love. I'm sure there are many of you who remembers their songs by heart.
Here I'll present how original scratch of song "Hey Jude" may have look like provided it was written not on a paper napkin but in EPC "language" with ARIS. The only thing more we need a Tune Governance to perform this model in LIVE or karaoke mode.
PS the model was designed with ARIS Express running old Macintosh computer. I believe Beatles could afford to buy one.
