About our Tuning Forks Our tuning forks are made in the USA from a special Aluminum Alloy that is heat treated giving them a very pure tone. The single fundamental frequency will remain constant for many years and the non-tarnishing material will not rust or corrode. They tune each tuning fork by hand to an accuracy of .25% or better. Ohm Therapeutics Tuning Forks are fully guaranteed to stay in tune. We work with the premier tuning fork manufacturer in the US. Ohm Tuning Forks are made with a space & medical grade aluminum alloy and are precision tuned to within 0.5% of their indicated frequency. We have chosen not to color our forks to reduce environmental impact.
Tuning forks used by orchestras between 1750 and 1820 mostly had a frequency of A = 423.5 Hz, although there were many forks and many slightly different pitches. Standard tuning forks are available that vibrate at all the musical pitches within the central octave of the piano, and other pitches.urrently, the most common tuning fork sounds the note of A = 440 Hz, because this is the standard concert pitch, which is used as tuning note by some orchestras, it being the pitch of the violin's second string, the first string of the viola, and an octave above the first string of the cello, all played open.
