The Human Ear A sound wave, like any other wave, is introduced into a medium by a vibrating object.
Concert pitch Since some instruments in an orchestra use different key signatures because of transposition"concert pitch" describes a particular pitch in absolute terms, regardless of notation. Labeling pitches Edit Pitches are often labeled using Pitch perception pitch notation or some combination of a letter and a number representing a fundamental frequency.
For example, one might refer to the A above middle C as "A4" or "A First, in standard Western equal-temperament, the notion of pitch is insensitive to spelling: Distance in this space corresponds to musical distance as measured in psychological experiments and understood by musicians.
The system is flexible enough to include "microtones" not found on standard piano keyboards. Varying pitch Edit Pitches may be described in various ways, including high or low, as discrete or indiscrete, pitch that changes with time chirping and the manner in which this change with time occurs: Musically the frequency of specific pitches is not as important as their relationships to other frequencies — the difference between two pitches can be expressed by a ratio or measured in cents.
People with a sense of these relationships are said to have relative pitch while people who have a sense of the actual frequencies independent of other pitches are said to have " absolute pitch ", or "perfect pitch".
Scales Edit The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems.
In the west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two or about 1.
In well-tempered systems as used in the time of Johann Sebastian Bachfor exampledifferent methods of musical tuning were used.
Almost all of these systems have one interval in common, the octavewhere the pitch of one note is double the frequency of another.The timing of responses in auditory nerve fibres (see Fig.
, FP p.
98). The timing theory of pitch perception proposes that pitch is determined by the timing of neural impulses in the auditory nerve. As phase locking breaks down for frequencies above 4 kHz, pitch perception based on timing information is only possible for low-frequency sounds.

An amazing discovery into your personal musical talent. In classical times. Most pitchers who brag about their rise ball don't really have one..
The majority of pitchers don't put the correct bottom-to-top spin on the ball, or don't have enough spin speed, or lack pitch speed.. Just because a pitcher releases the ball low and throws it high on the batter doesn't mean it is a rise ball.
While working at the music and neuroimaging lab at Beth Israel/Harvard Medical School in Boston, I developed a quick online way to screen for the tonedeafness. It actually turned out to be a pretty good test to check for overall pitch perception ability. The test is purposefully made very hard, so excellent musicians rarely score above 80% correct.
The ability of humans to perceive pitch is associated with the frequency of the sound wave that impinges upon the ear. Because sound waves traveling through air are longitudinal waves that produce high- and low-pressure disturbances of the particles of the air at a given frequency, the ear has an ability to detect such frequencies and associate them with the pitch of the sound.
