432Hz Tuning Fork
When tuning forks were first invented, they were invented to tune musical instruments. But when Shore invented the tuning forks, there was no standard pitch at the time. Some orchestra’s used different pitches for their A note. The problem came in when one orchestra player had to move to another location and tried to play in the orchestra of the new country that they were in, and they found that they were off key. As more musicians began to travel around the country, they discovered that they needed to have a standard pitch to which they could all tune their instruments to.
At first, in the middle 1800s in France, we had the Continental Pitch which set the pitch of A to 435 Hz. Later in that same century in England, the New Philharmonic Pitch set A to 439 Hz. By the 1900s, the International Concert Pitch became 440 Hz for the A note. The Concert Pitch is still in use to this day worldwide. The 440 Hz is the pitch of the violin’s second string and the pitch of the viola’s first string.
The tuning fork that was first used in the 1700s and early 1800s had an A frequency of 423.5 Hz. When the concert pitch changed, the frequency of the tuning changed to match it. Today, when looking at the music tuning forks, the A frequency is stamped right on the fork as A=440 Hz.
