What a horrendous article. My favorite part is:
Notice how the top line has almost five million (approx.) as many black dots as the second line? That top bit is the soloist, who is carrying the melody while everyone else is chugging along playing long tones. There is only one soloist, thus the name. So if you're in an orchestra, you're almost certainly in that "everyone else" category, basically serving as bland background noise for the guy everyone came to hear.
Not enough eye-rolling for this.
