A Musical Analogy That Can Be Applied to Democratic Primary Politics, Perhaps.

6. Interesting history.

I've always played in bands that usually tune from the bottom up - starting with the tuba with the other voices joining from low to high, first the other bass/baritone voices (euphoniums, bassons, bass clarinets, baritone sax), next the tenor trombones, next the alto voices (alto sax and horns); to trumpets, and ending with the clarinets, flutes and oboe. In my high school and college days, bands tuned to a B-flat. These days the band tunes to an F. (Tuning to F is really helpful to trombones that have an F-attachment - where concert F is played in first position on both the B-flat and F side.) Then, someone who can be relied upon sounds an A for the saxes, clarinets and flutes.

The benefit of cellphone and other small electronic tuners is that every should be close to tuned to the 440-A standard before the band is tuned.

To your analogy, the 440-A is accepted as truth. The country would be greatly improved if we could agree on obvious truths.
