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.
In music, an octave (Latin: octavus: eighth) or perfect octave (sometimes called the diapason) [2] is an interval between two notes, one having twice the frequency of vibration of the other. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical ...
The music program Logic Pro uses also 1 ⁄ 2-comma meantone temperament. Equal-tempered refers to X-tone equal temperament with intervals corresponding to X divisions per octave. Tempered intervals however cannot be expressed in terms of prime limits and, unless exceptions, are not found in the table below.
A jump from the lowest semitone to the highest semitone in one octave doubles the frequency (for example, the fifth A is 440 Hz and the sixth A is 880 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).
Octave clef Treble and bass clefs can be modified by octave numbers. An "8" below the clef (as in the third diagram) indicates that pitches will sound an octave lower than they would with the unmodified clef. A "15" below indicates a two-octave shift. These numbers may also be used above the clef to indicate pitches one or two octaves higher.
Pitch is a perceptual property that allows sounds to be ordered on a frequency-related scale, [1] or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. [2] Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre ...
The ordered pitch-class interval describes the number of ascending semitones from one pitch-class to the next, ordered from lowest to highest. Since pitch-classes have octave equivalence, the ordered pitch -class interval can be computed mathematically as "the absolute value of the difference between the two pitch-classes modulo 12".
The naming of individual Cs using the Helmholtz system. Helmholtz pitch notation is a system for naming musical notes of the Western chromatic scale.Fully described and normalized by the German scientist Hermann von Helmholtz, it uses a combination of upper and lower case letters (A to G), [a] and the sub- and super-prime symbols ( ͵ ′ or ⸜ ⸝) to denote each individual note of the scale.
