  2. Octave effect - Wikipedia

    en.wikipedia.org/wiki/Octave_effect

    Octave effect boxes are a type of special effects unit which mix the input signal with a synthesized signal whose musical tone is an octave lower or higher than the original. The synthesised octave signal is derived from the original input signal by halving (octave-down) or doubling (octave-up) the frequency.

  3. Pitch circularity - Wikipedia

    en.wikipedia.org/wiki/Pitch_circularity

    Because the octave is the most consonant interval after the unison, tones that stand in octave relation, and are so of the same pitch class, have a certain perceptual equivalence—all Cs sound more alike to other Cs than to any other pitch class, as do all D ♯ s, and so on; this creates the auditory equivalent of a Barber's pole, where all ...

  4. Pitch space - Wikipedia

    en.wikipedia.org/wiki/Pitch_space

    The simplest pitch space model is the real line. A fundamental frequency f is mapped to a real number p according to the equation = + ⁡ (/) This creates a linear 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, as it is in MIDI. 440 Hz is the standard frequency of 'concert A', which ...

    Successive Z-related hexachords from act 3 of Wozzeck [4]: 79 Play ⓘ. In musical set theory, a Z-relation, also called isomeric relation, is a relation between two pitch class sets in which the two sets have the same intervallic content (and thus the same interval vector) but they are not transpositionally related (are of different T n-type ) or inversionally related (are of different T n /T ...

  7. Pitch class space - Wikipedia

    en.wikipedia.org/wiki/Pitch_class_space

    In music theory, pitch-class space is the circular space representing all the notes (pitch classes) in a musical octave. In this space, there is no distinction between tones separated by an integral number of octaves. For example, C4, C5, and C6, though different pitches, are represented by the same point in pitch class space.

  9. Pseudo-octave - Wikipedia

    en.wikipedia.org/wiki/Pseudo-octave

    A pseudo-octave, pseudooctave, [1] or paradoxical octave [2] in music is an interval whose frequency ratio is not exactly 2:1 = octave : tonic expected for perfectly harmonic pitches, but slightly wider or narrower in pitch – for example 1.98:1, 2.01:1, or even as large as 2.3:1 . [1]
