Chapter 11- Music and Speech Perception Flashcards
Pitch
The psychological aspect of sound related mainly to perceived frequency.
Octave
The interval between two sound frequencies having a ratio of 2:1.
Tone Height
A sound quality corresponding to the level of pitch. Tone height is monotonically related to frequency.
Tone Chroma
A sound quality shared by tones that have the same octave interval.
Chord
A combination of three or more musical notes with different pitches played simultaneously.
Absolute Pitch (AP)
A rare ability whereby some people are able to accurately name or produce notes without comparison to other notes.
Melody
A sequence of notes or chords perceived as a single coherent structure.
Tempo
The perceived speed of the presentation of sounds.
Rhythm
A repeated pattern of sounds comprised of strong and weak elements.
Syncopation
Any deviation from a regular rhythm.
Vocal Folds
The pair of elastic tissues that vibrate due to airflow generated by lungs, depending on how close or apart and how tense or lax they are.
Phonation
The process through which vocal folds are made to vibrate when air pushes out of the lungs.
Vocal Tract
The airway above the larynx used for the production of speech. This includes the oral tract and nasal tract.
Articulation
The act or manner of producing a speech sound using the articulators- vocal tract structures including the mouth, tongue, soft palate, and jaw.
Resonator
Most objects such as musical instruments and vocal tracts are resonators because, due to their shape, they increase amplitude at some frequencies, called resonant frequencies, compared to other frequencies.
