Why A Minor is the best chord...

My husband Evan believes that A Minor is the best chord that one can play either on guitar or other instruments that allow you to play chords. He is quoted as saying that "Stairway to Heaven is nothing without it!"
I would tend to agree that A Minor is a nice chord. But the best? Go find a guitar or a piano and find out for yourself...
Here's our friend Cory...probably playing an A Minor chord.
