Pitch is perceived as how "low" or "high" a sound is and represents the cyclic, repetitive nature of the vibrations that make up sound. For simple sounds, pitch relates to the frequency of the slowest vibration in the sound (called the fundamental harmonic). In the case of complex sounds, pitch perception can vary.
Only 10% of languages, including English, have a vowel diagram that is quadrilateral. Such a diagram is called a vowel quadrilateral or a vowel trapezium. [2] Different vowels vary in pitch. For example, high vowels, such as [i] and [u], tend to have a higher fundamental frequency than low vowels, such as [a]. Vowels are distinct from one ...
Therefore, a contour that follows the sequence of low, middle, high, would be labeled as contour classes 0, 1, and 2. Pure tones have a clear pitch, but complex sounds such as speech and music typically have intense peaks at many different frequencies. Nevertheless, by establishing a fixed reference point in the frequency function of a complex ...
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 ...
For example, Mandarin Chinese has four lexical tones. The high tone is level, without contour; the falling tone is a contour from high pitch to low; the rising tone a contour from mid pitch to high, and, when spoken in isolation, the low tone takes on a dipping contour, mid to low and then to high pitch.
Scales are typically listed from low to high pitch. Most scales are octave-repeating, meaning their pattern of notes is the same in every octave (the Bohlen–Pierce scale is one exception). An octave-repeating scale can be represented as a circular arrangement of pitch classes, ordered by increasing (or decreasing) pitch class.
Very high pitch is for strong emotion or emphasis. [21] Pitch can indicate attitude: for example, Great uttered in isolation can indicate weak emotion (with pitch starting medium and dropping to low), enthusiasm (with pitch starting very high and ending low), or sarcasm (with pitch starting and remaining low).
For example, a female singer may have a vocal range that encompasses the low notes of a mezzo-soprano and the high notes of a soprano. A voice teacher would therefore look to see whether the singer was more comfortable singing higher, or lower. If she were more comfortable singing higher, then the teacher would probably classify her as a soprano.
