![]() Ptolemy started using justintonation in 136 AD. Like standard pitch A440, equal temperament is not the onlytuning scale that has been used. The roughness is called the "wolf." This term may have come about because if the "wolf" is not set right the instrument will be howling out of tune. ![]() ![]() This sets the pitches of the twelve notes so that the player can play the instrument in all keys by dividing the roughness equally among the twelve notes. The most common system used to day is known as equal temperament. A scale is set in the middle and this scale also determines the pitch of all the twelve notes in the octave. Of course, once you have your "A" or "C" set to a pitch, the rest of the instrument will have to be tuned. In December 1939 the BSI published a book called "British Standard Concert Pitch" The BSI committee passed a resolution for a pitch of A440 at 68F.

The conference finished with no full agreement on pitch only that each country should set up subcommittee to look at the problem. The mathematician Sir James Swinburne put the case for A440 on the grounds it rounded numbers up and made calculation in the scale simple. The conference studded the matter at great length, quite a few where in favour of a pitch of A439 tep: 68 F. In May 1938 an international conference was set up to look at a universal pitch. He was the sergeant trumpeter to the Court and also lutenist in the Chapel Royal. The tuning fork was invented by John Shore in 1711 and it had a pitch of A423.5. However, in the past, pitch pipes have been used, and today electronic tuning forks are also used, but the most common is the tuning fork. A tuning fork is normally used to set the pitch. A form of standard pitch has been around ever since two individuals wished to play two instruments together or sing to an instrument. Today’s standard pitch is A440 orC523.3 and this concert pitch enables musicians to play instrumentstogether in harmony.
