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 approximately 261.63 Hz, [1] making it approximately 31.77 cents lower than the common A440 pitch standard.
Scientific pitch notation is often used to specify the range of an instrument. It provides an unambiguous means of identifying a note in terms of textual notation rather than frequency, while at the same time avoiding the transposition conventions that are used in writing the music for instruments such as the clarinet and guitar.
Concert pitch is the pitch reference to which a group of musical instruments are tuned for a performance. Concert pitch may vary from ensemble to ensemble, and has varied widely over time. The ISO defines international standard pitch as A440, setting 440 Hz as the frequency of the A above middle C. Frequencies of other notes are defined ...
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.
Scientific pitch was originally proposed in 1713 by French physicist Joseph Sauveur and based on the numerically convenient frequency of 256 Hz for middle C, all C's being powers of two. After the A440 pitch standard was adopted by musicians, the Acoustical Society of America published new frequency tables for scientific use.
For a classical piano and musical theory, the middle C is usually labelled as C 4 (as in scientific pitch notation); However, in the MIDI standard definition this middle C (261.626 Hz) is labelled C 3. In practice, a MIDI software can label middle C as C 3-C 5, which can cause confusion, especially for beginners.
Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration (audio frequency). [5] Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute which can be measured.
"The pitch class C stands for all possible Cs, in whatever octave position." [1] Important to musical set theory, a pitch class is "all pitches related to each other by octave, enharmonic equivalence, or both." [2] Thus, using scientific pitch notation, the pitch class "C" is the set {C n : n is an integer} = {..., C −2, C −1, C 0, C 1, C 2 ...
