Diversity

 

Seventy Six Trombones

Seventy-six trombones led the big parade
With a hundred and ten cornets close at hand
They were followed by rows and rows

Of the finest virtuosos

The cream of ev'ry famous band
Seventy-six trombones caught the morning sun
With a hundred and ten cornets right behind
There were more than a thousand reeds
Springing up like weeds
There were horns of ev'ry shape and kind

IOW, that parade is NOT just trombones

Typical is NOT a synonym for normal.  In statistics, typical is the mode, the most common value of a distribution.  It is not the ONLY value in a distribution.  A normal distribution is one where the skew is close to zero and we don’t always expect the mean to be equal to the median.  Why then would we expect the mode to be equal to the mean.

A parade of only trombones would be silly.  An orchestra of only one type of instrument would NOT be an orchestra.  A string quartet consists of violins, violas, and cellos.  A barbershop quartet consists of baritone, bass and tenor voices singing in harmony. Diversity in music is why there is harmony.  In life, diversity is a good thing as well. If diversity is harmony then the opposite of diversity must be discord.
