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.
A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
The initial standard was A = 439 Hz ⓘ, but this was superseded by A = 440 Hz, possibly because 439 Hz was difficult to reproduce in a laboratory since 439 is a prime number. [22] In 1964, of 31 top professional U.S. orchestras, 19 were tuning at 440, the others at 441 or 442. [23]
When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the F ♯ above middle C (or F ♯ 4) is approximately 369.994Hz. [1] See pitch (music) for a discussion of historical variations in frequency.
Undertone series on C. [1] In music, the undertone series or subharmonic series is a sequence of notes that results from inverting the intervals of the overtone series.While overtones naturally occur with the physical production of music on instruments, undertones must be produced in unusual ways.
Apollo 440 (also known as Apollo Four Forty or @440) are an English electronic music group formed in Liverpool in 1990. [1] The group has written, recorded, and produced five studio albums, collaborated with and produced other artists, remixed as Apollo 440 and as ambient cinematic alter-ego Stealth Sonic Orchestra, and created music for film, television, advertisements and multimedia.
For many years, there was no pitch standard across Europe. The frequency of a ′ (the standard note for tuning musical instruments), for example, could range from a ′ =392 Hz in parts of France to a ′ =465 Hz (Cornet-ton pitch) in parts of Germany. [1] [2] Organs were often tuned differently than ensembles, even within the same region or town.
A spectrogram of ascending Shepard tones on a linear frequency scale A Shepard tone , named after Roger Shepard , is a sound consisting of a superposition of sine waves separated by octaves . When played with the bass pitch of the tone moving upward or downward, it is referred to as the Shepard scale .
