These tuning fork sounds were professionally recorded from real tuning forks placed onto an amplified sounding board.
The "tuning fork" was invented by John Shore, English musician to the royal court in 1711 and had a pitch of A423.5. The numbers underneath the musical notes represent the Hertz (Hz) or cycles per second of the sound wave made when the fork is vibrating.
Standard Pitch or Concert Pitch is a universal frequency or note that all musical instruments are tuned to. Today's standard pitch is A440 or C523.3 and this enables musicians to play instruments together in harmony, without clashing pitches. A tuning fork is normally used to set the pitch. Pitch pipes and electronic tuning forks can also be used, but are not as common.
