A sound or note of definite pitch is one where a listener can possibly (or relatively easily) discern the pitch. Sounds with definite pitch have harmonic frequency spectra or close to harmonic spectra. [11] A sound generated on any instrument produces many modes of vibration that occur simultaneously. A listener hears numerous frequencies at once.
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
Tone is the use of pitch in language to distinguish lexical or grammatical meaning—that is, to distinguish or to inflect words. [1] All oral languages use pitch to express emotional and other para-linguistic information and to convey emphasis, contrast and other such features in what is called intonation, but not all languages use tones to distinguish words or their inflections, analogously ...
One or "a" (indefinite article), as exemplified in the following entries un poco or un peu (Fr.) A little una corda One string (i.e., in piano music, depressing the soft pedal, which alters and reduces the volume of the sound). For most notes in modern pianos, this results in the hammer striking two strings rather than three.
A pure tone's pressure waveform versus time looks like this; its frequency determines the x axis scale; its amplitude determines the y axis scale; and its phase determines the x origin. In psychoacoustics, a pure tone is a sound with a sinusoidal waveform; that is, a sine wave of constant frequency, phase-shift, and amplitude. [1]
The teacher would also consider the sound of the voice; sopranos tend to have a lighter and less rich vocal sound than a mezzo-soprano. A voice teacher, however, would never classify a singer in more than one voice type, regardless of the size of the vocal range of the singer. [2]
[18] Absolute pitch is an act of cognition, needing memory of the frequency, a label for the frequency (such as "B-flat"), and exposure to the range of sound encompassed by that categorical label. Absolute pitch may be directly analogous to recognizing colors , phonemes (speech sounds), or other categorical perception of sensory stimuli .
Pitch (music), the perceived frequency of sound including "definite pitch" and "indefinite pitch" Absolute pitch or "perfect pitch" Pitch class, a set of all pitches that are a whole number of octaves apart; Relative pitch, the ability to identify a given musical interval between two notes; Pitch accent, a form of accentuation in speech
