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 ...
Concert pitch is the pitch reference to which a group of musical instruments are tuned for a performance. Concert pitch may vary from ensemble to ensemble, and has varied widely over time. The ISO defines international standard pitch as A440, setting 440 Hz as the frequency of the A above middle C. Frequencies of other notes are defined ...
Absolute pitch (AP), often called perfect pitch, is the ability to identify or re-create a given musical note without the benefit of a reference tone. [1] [2] AP may be demonstrated using linguistic labelling ("naming" a note), associating mental imagery with the note, or sensorimotor responses.
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.
In baseball, the pitch is the act of throwing the baseball toward home plate to start a play. The term comes from the Knickerbocker Rules . Originally, the ball had to be thrown underhand, much like "pitching in horseshoes" .
To represent pitch classes, we need to identify or "glue together" all pitches belonging to the same pitch class—i.e. all numbers p and p + 12. The result is a cyclical quotient group that music theorists call pitch class space and mathematicians call R /12 Z .
The pitch is prepared differently from the rest of the field, to provide a harder surface for bowling. A pitch is often a regulation space, as in an association football pitch. The term level playing field is also used metaphorically to mean fairness in non-sporting human activities such as business where there are notional winners and losers. [1]
