  • psychoacoustics

    the study of the perception of sound

    perception

    the cognitive process of assigning meaning to aural sensory input

    critical band

    area on the basilar membrane that displaces in response to a particular frequency, usually encompasses 3-4 frequencies

    periodicity pitch theory

    theory of pitch perception based on pattern recognition set by the pattern of return of the fundamental frequency . . . the quality of something recurring regularly

    gestalt

    a school of psychology emphasizing pattern recognition and grouping of sensory input into the unified whole

    law of common fate

    a gestalt principle stating that when events occur together, we learn to perceive them as a unit.

    periodicity

    the tendency of something to recur at regular intervals

    discrimination

    the ability to perceive differences in sensory input

    difference limen

    the number of frequencies you need to say there is a different pitch sounding 50% of the trials (if you can tell the difference between 440 and 444 50% of the time, you have a ______________ of 4)

    perfect pitch

    the ability to name the pitch of a tone without having to compare it to a standard or comparison tone - also involved the ability to produce a specific pitch on demand (aka "absolute" ______

    combination tone

    occurs when two loud tones are sounded together, a third tone is heard that is not actually present in the audible sound.

    loudness

    perception of amplitude (intensity)

    masking

    when one audible sound by itself can become inaudible in the presence of another sound

    volume

    the apparent size of extensity of sound (tuba has more _______ than flute)

    density

    apparent compactness or diffusion of sound

    timbre

    parameter of sound that distinguishes one tone from another even if the two tones have the same frequency and amplitude

    tone quality

    related to timbre and is variations that can occur within a timbre range

    partials

    any component of a complex tone, including the fundamental

    formants

    areas of resonance in an instrument

    vibrato

    rapid frequency modulation; periodic variation of the tone (amplitude also changes, adds to timbre)

    Consonance

    sound that is generally considered to be pleasing or stable

    Dissonance

    sound that is generally considered to be unpleasant, disturbing, discordant, or rough

    Interval

    space between notes; expressed in ratio relationships

    Scale

    a pattern of audible frequencies arranged in any ascending or descending order

    Tuning

    refers to precise relationship between frequency being played and a standard for comparison

    Temperament

    adjustment of tones and intervals to make a simpler, more practical scale

    Pentatonic Scale

    a five-note scale, which is a natural outgrowth of the fourth and fifth that was seen in early Greek musical theory as the most consonant

    Note

    individual frequency in the scale arrangement

    Pythagorean Scale

    early Greek musical scale created by projecting an ascending series of pure fifths and then dropping an octave to create stepwise movement until a chromatic scale was completed.

    Pythagorean comma

    the interval between the chromatic and diatonic semitones in the pythagorean scale

    just intervals

    simple, whole number interval ratios

    syntonic comma

    interval between the major and minor third in the pythagorean scale

    enharmonics

    in equal temperament when a sharp and a flat are the same pitch, ex - g sharp and a flat

    Just intonation

    scale based on consonant note pairs

    Meantone Intonation

    tuning system considered unequal temperament and created by sacrificing the pure perfect fifth in favor of one size for each interval

    Equal Temperament

    tuning system created by dividing the octave into twelve equal semi-tones

    Melody

    successive combinations of tones placed in a temporal sequence

    contour

    the overall shape in space of the pattern of up and down movement when considering pitch relationships within the melody

    propinquity

    relative closeness of tones, proximity

    tonality

    "loyalty" to a primary tone or tonic

    Harmony

    simultaneously sounding individual tones, vertical pitch structure

    Rhythm

    the temporal pattern that tonal stimuli follow

    rhythmic unit groups

    basic rhythmic units; building blocks of musical rhythms (iamb, trochee, dactyl, anapest, amphibrach, single beat, tremolo)

    iamb

    weak/strong
    -/

    trochee

    strong/weak
    /-

    dactyl

    strong/weak/weak
    /--

    anapaest

    weak/weak/strong
    --/

    amphibrach

    weak/strong/weak
    -/-

    single beat

    strong/strong/strong
    ///

    tremolo

    weak/weak/weak
    ---

    rhythmic line

    two or more rhythmic units combined

    rhythmic pattern

    combinations of rhythmic lines

    beat

    the pulse; underlying structural component of rhythm

    meter

    pattern of grouping of regularly recurring beats

    syncopation

    occurs when beats are accentuated apart from the regular metrical pattern

    tempo

    speed or pace at which the beat occurs

    accent

    emphasis of a beat

    personal tempo

    rate of speed of spontaneous rhythmic movements, unique to each individual

    mentalist

    belief that no human ability or behavior was learned or gained from interaction with the environment

    musical mind

    Seashore's factors of musical talent
