MUSIC THEORY – Why is A = 440 Hz ?

In this music theory animated tutorial made by Walk That Bass, you are going to understand why we use 440 Hz as a standard tuning for musicians.

In the past, there was no international ‘standard tuning’. So a flute from France was tuned to a different note than a flute from England. Over the past 500 years, so since Medieval and early Renaissance times, the pitch of the note A (and therefore all the notes) has risen by about a minor third, but with large variations throughout. In the early 17th century, pitch levels ranged by as much as a Perfect 5th. This, obviously, wasn’t very efficient.

So after a lot of discussion, an international conference in London in 1939 decided that the A above middle C was to be tuned to 440 Hz in all countries from then on. This is known as the ‘international standard pitch’ or ‘concert pitch’.
