This would also be a good place to bring up that some music theory people don’t consider two-note intervals “chords.” But my take on that whole controversy is that, when naming things, it should be taken into account how our brains ascertain tonal information based on everything we’ve heard before, in all of music. It’s just something our brains do, so why deny it because we selfishly want a more tidy nomenclature?
The problem is that these tendencies are the exact opposite of what we should be doing if we want to see real improvement, according to Dr. Anders Ericsson. And we might be wise to listen. Dr. Ericsson is widely considered one of the foremost thinkers on the subject of “expertise.” His research is one of the primary sources that inspired Malcolm Gladwell’s now-famous “10,000 Hour Rule” — that it takes 10,000 hours of deliberate practice to be an expert in anything. But that rule, though memorable, is far from the whole story.
