Scientific pitch, also known as philosophical pitch, Sauveur pitch or Verdi tuning, is an absolute concert pitch standard which is based on middle C (C 4) being set to 256 Hz rather than ~ 261.63 Hz, [a] making it ~ 31.77 cents lower than the common A440 pitch standard.
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
The global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances are the principal background in the part of the electromagnetic spectrum [2] from 3 Hz through 60 Hz [3] and appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz.
The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463). [ 1 ] [ 2 ] For example, to get the frequency one semitone up from A 4 (A ♯ 4 ), multiply 440 Hz by the twelfth root of two.

In 1983, Porsche did more than just win the 24 Hours of Le Mans. Its 956 prototype finished 1-2-3-4-5-6-7-8, another 956 rounded out the top ten, and the top-finishing grand tourer was a 911-based ...
The company started as Viva 963, broadcasting on terrestrial radio, predominantly for women, and was later renamed. It lost its terrestrial broadcasting licence in 2002 after being acquired by the Universal Church of the Kingdom of God (UCKG); the broadcasting slot was taken over by Buzz Asia , with different content.
