Scientific pitch is an absolute pitch standard that sets middle C (or C4) to 256 Hz. It was introduced in the early 20th century. A4 on this scale is approximately 431 Hz, noticeably different from the current concert pitch standard of 440 Hz. It is no longer used by concert orchestras but is still sometimes favoured in scientific writings for the convenience of all the octaves of C being an exact round number in the binary system. For example, this frequency for middle C, 256 Hz, can be represented by (100000000)two. More usefully, the octaves of C remain a whole number all the way down to 1 Hz (in either counting system).

Famous quotes containing the words scientific and/or pitch:
“Thus will the fondest dream of Phallic science be realized: a pristine new planet populated entirely by little boy clones of great scientific entrepeneurs ... free to smash atoms, accelerate particles, or, if they are so moved, build pyramids—without any social relevance or human responsibility at all.”
—Barbara Ehrenreich (b. 1941)
“It is beyond a doubt that during the sixteenth century, and the years immediately preceding and following it, poisoning had been brought to a pitch of perfection which remains unknown to modern chemistry, but which is indisputably proved by history. Italy, the cradle of modern science, was at that time, the inventor and mistress of these secrets, many of which are lost.”
—Honoré De Balzac (1799–1850)
