  A paradox of musical pitch
The 12 pitch classes can be thought of in a circle; one trip around the circle (from C to C) is an octave; halfway around (from C to F#) is an interval called a tritone.
And when the peak pitch classes of the younger Vietnamese group were compared with native Californians of the same age, the differences remained highly significant.
Odds are that pitch class templates are developed at a very young age--perhaps as infants listen to the intonation of voices around them.

Pitch class is important because human pitch-perception is periodic: pitches belonging to the same pitch class are perceived as having a similar "quality" or "color." Psychologists refer to the quality of a pitch as its "chroma"; the music theorists use the term "pitch class" instead.
This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and middle C is assigned the number 60.

  Pitch class Information
Human pitch-perception is periodic: pitches separated by an integral number of octaves are perceived as having a similar "quality" or "color." Psychologists refer to the quality of a pitch as its "chroma." Music theorists typically use the term "pitch class" rather than "chroma."
A "pitch class" is a set of all pitches sharing the same chroma, just like "the set of all white things" is the collection of all white objects.
This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and middle C is assigned the number 60.

 Tritone Paradox and Spectral-Motion AfterEffects
If you were to envision the 12 chromatic pitches in series as the numbers on the face of a clock, pairs in which the first member is in the upper half of the clock will result in more descending perceptions, and those in the bottom with more ascending perceptions.
Pitch classes at the top or bottom of "the clock" are the least ambiguous.
This may indicate that the orientation of the pitch class circle is malleable, and changes to match a prevalent mode within a geographical area.

 Pitch class
In music and music theory a pitch class contains all notess that have the same name; for example, all Es, no matter which octave they are in, are in the same pitch class.
In musical set theory it is more accurate to say that a pitch class is an equivalence class of all pitcheses that are octaves apart, which would be labeled by an integer, not a traditional letter name.
In both cases, when "pitch class" is used, the use of "pitch" indicates a specific frequency or note and does not include its octaves.

 § 27. frequency / pitch / pitch class. 4. Science Terms. The American Heritage Book of English Usage. 1996
Typical pitch standards in Western music assign a given frequency to one of the twelve notes in an octave: C, C#, D, D#, E, F, F#, G, G#, A, A#, B, and another symbol to indicate the relative position of the octave.
The pitch class of a sound is determined only by its note assignment and not by the octave in which the note occurs.
In acoustics, a unit of pitch called the mel (from melody) has a dependence on the frequency and the intensity at which a note is heard.

A third assumption upon which the analytic procedure is based is that the frequency of a pitch class in a PC string is a defining linear characteristic of the melody from which that string is derived.
Secondly, the pitch classes of the tonic triad emerge in sharp relief as represented by the longer durational symbols of whole, half, and quarter notes.
Finally, the fourth-, fifth-, and sixth-class pitch classes (symbolized by eighth-, sixteenth-, and thirty-second notes in the paradigms of Example 3) suggest a second harmonic structure that is expanded in the melody: an E minor triad.

Indeed many interesting types of pitch organization are realizable only with the aid of a computer due to their complexity, level of abstraction, or amount of calculation required.
If a certain target pitch set is used as the fitness measurement for offspring in an evolving population, and pitches and chords are continually chosen from the existing population, then over time, this creates a gradual modulation from one type of population (one harmonic setting) to another.
The pitch class set in use at any given instant is determined by what pitch classes are present (vertically) as one moves from left to right (from C to A-flat).

 [Smt-talk] Pitch-class dogmas
Pitch-classes result from a property of the intervals between pitches related by octave multiples, as we hear them, but it is a very strange and extremely fragile property, one that is extremely easy to deconstruct (to cancel).
Having reliable images of these pitches, they quickly acquire a sense of octave equivalence as a necessary operating procedure in our culture, on the same basis as does everyone else, and generalize their memories of pitches to memories of octave classes.
Pitch is linear but it does not flow, in and of itself, from lower to higher, or in the other direction.

Pitch Class Numbers In the dodecatonic scale (the chromatic scale), each pitch class can be assigned a number from 0 through 11 to indicate its position in the chromatic octave.
The initial pitch is numbered 0 and serves as a reference for the numbering of the other pitches.

The pitches are numbered according to their position in the chromatic scale beginning on E. E is numbered 0 because it is the first note of the row or the reference pitch.

The pitch class number in any square is the sum of the numbers at the beginning of its row and the top of its column.

Count from one pitch class to the other by the shortest route possible, whether this is up or down.
Similar to pitch classes, each interval class incorporates a number of individual pitch intervals that are considered equivalent: compound intervals (larger than an octave) are considered to be equivalent to their corresponding interval within the octave and intervals larger than 6 (tritone) are considered equivalent to their inversion within the octave.

 Dolmetsch Online - Music Theory Online - Staffs, Clefs & Pitch Notation
The clef establishes the pitch of the note on one particular line of the staff and thereby fixes the pitch of all the other notes lying on, or related to, the same staff.
In integer notation, or the integer model of pitch, all pitch classes and intervals between pitch classes are designated using the numbers 0 through 11.
Pitch classes can be notated in this way by assigning the number 0 to some note - C natural by convention - and assigning consecutive integers to consecutive semitones; so if 0 is C natural, 1 is C sharp, 2 is D natural and so on up to 11 which is B natural.

 All About Musical Set Theory
Keep in mind that sets and set classes determined pitch content only; the composers remained free to fashion all other aspects of the music according to their artistic desires (at least until super-serialism, a philosophy of subjecting every aspect of the music to serial techniques, came into fashion in the 1950s).
Pitch sets can be put into Normal Form, which is an ordering of the pitches in the set which is deemed the most "compact." Compact ordering means that the largest of the intervals between any two consecutive pitches is between the first and last pitch listed.
There is one occurence of interval class 1 (between the 2 and the 3), one occurence of interval class 6 (between the 3 and the 9) and one occurence of interval class 5 (between the 2 and the 9).

 What Is "The Matrix"?
The term "pitch class" (abbreviated "pc") employs the notion of octave equivalence and refers to any member of the set of pitches of the same "name" (i.e.
So in the case of inversional equivalence, the equivalence will be assumed for the purposes of identifying pc sets by their equivalence classes, but it may often be more useful to distinguish between a sonority and its inversion.
The analysis of music based on parsing melodies and chords into these small collections of pitch classes is useful in non-functional music where no serial process is involved, and also it can be useful in analyzing the construction of a particular tone row and the atonal results of its use in a complex work.
