What is concert tuning? What does A440 mean? Why should one get it or not get it?

 

I recommend concert tuned instruments if you are wanting to play with others or record with other tuned instrumentation. 

This is much harder to make as each note has to be perfect pitch on an electronic meter and built at the right temperature. There are times I might need to make 5 flutes or saxes before one comes out perfect pitch in concert tuning, so it is more expensive. 

Flutes tuned to themselves are just fine for playing alone. The work of a good Flutemaker is to make good sounding in tune flutes to themselves and also provide professionally tuned instruments to play with others.

History of tuning:

Europe needed to have a universal standard of tuning because the pitches in Europe kept changing for different reasons.

 One reason was old church organs going bad would be cut off at the top causing the pitch to rise. Another reason was it became popular to make a new wind instrument brighter than a former competitor giving the people a feeling of a new chirpier sound from an the dull past sound. Then pitch was raised to better hear brighter higher notes and louder music in large public hall concerts . This became a problem for opera singers singing along which caused their voices to strain.  Higher tuning was bad for pianos causing strings, plate and the back to be strained. Also due to the raise in pitch stringed instruments began popping strings. So in 1859 France passed a law making the note A legal at 435 HZ.  at 59 degrees F.

In 1896 The London Philharmonic Society tuned at A439 degrees at 68 degrees F considered room temperature and said when the French tuned at 59 degrees F. it was the same just as if they were tuning to A439 at 68 degrees F. The standard today is to tune to A440 at 72 degrees F. which was the temperature set to warm the concert halls of Europe.

In 1939, 3 months before world war 2 broke out, a music convention of Europeans held  in Britain decided to make the universal standard at A440. Folks went back home and prepared for war and when the dust settled in 1955 they retuned to confirm that when the note A vibrated at 440 vibrations per second, that would be considered the universal standard of the A note so the world could play together in tune.
