I understand the point that's being made here, but when you understand music this analogy doesn't quite stand up. The final chord in a piece of music may indeed be the most important, but it only works when preceded by all the other notes and chords performed in the correct sequence and tempo. Therefore, to rush a piece of music, or to only play the final chord, it wouldn't have the same effect as if it was preceded by the rest of the music. But that doesn't mean the last chord isn't the most important part. This logic could apply to anything. You might say that the CEO is the most important person in a company, but that doesn't mean the other members of staff are not important. If the company was only the CEO, it wouldn't be able to function, but just because the CEO needs all the other members of staff doesn't mean they're not the most important person in the company.
