[pich]
pitch, in aviation: see airplane; airfoil.
pitch, in music, the position of a tone in the musical scale, today designated by a letter name and determined by the frequency of vibration of the source of the tone. Pitch is an attribute of every musical tone; the fundamental, or first harmonic, of any tone is perceived as its pitch. The earliest successful attempt to standardize pitch was made in 1858, when a commission of musicians and scientists appointed by the French government settled upon an A of 435 cycles per second; this standard was adopted by an international conference at Vienna in 1889. In the United States, however, the prevailing standard is an A of 440 cycles per second. Before the middle of the 19th cent., pitch varied according to time, place, and medium of musical performance; since the classical period the trend has been gradually upward. The relative pitch of a tone, in contrast to absolute pitch, is an expression of its pitch in relation to the pitch of some other tone taken as a standard.
pitch: see tar and pitch.

In music, position of a single sound in the complete range of sound; this quality varies with the number of vibrations per second (hertz, Hz) of the sounding body and is perceived as highness or lowness. A higher pitch has a higher number of vibrations. In Western music, standard pitches have long been used to facilitate tuning. A confusing variety of pitches prevailed until the 19th century, when the continual rise in pitch made some international agreement a matter of practical necessity. In 1939 the A above middle C was standardized as 440 Hz. Seealso interval; tuning and temperament.
