Scientific pitch, is also known as philosophical pitch, Sauveur pitch or Verdi tuning, and is an absolute concert pitch standard which is based on middle C (C4) being set to 256 Hz rather than approximately 261.63 Hz,[1] making it approximately 31.77 cents lower than the common A440 pitch standard. It was first proposed in 1713 by French physicist Joseph Sauveur, promoted briefly by Italian composer Giuseppe Verdi in the 19th century, then advocated by the Schiller Institute beginning in the 1980s with reference to the composer, but naming a pitch slightly lower than Verdi’s preferred 432 Hz for A, and making controversial claims regarding the effects of this pitch.
Scientific pitch is not used by concert orchestras but is still sometimes favored in scientific writings for the convenience of all the octaves of C being an exact power of 2 when expressed in hertz (symbol Hz).[2][3] The octaves of C remain a whole number in Hz all the way down to 1 Hz in both binary and decimal counting systems.[4][5] Instead of A above middle C (A4) being set to the widely used standard of 440 Hz, scientific pitch assigns it a frequency of 430.54 Hz.[6]
