(French: concrete music) A development introduced in Paris in 1948 by Pierre Schaeffer at the studio of the French Radio (O.R.T.F.). Its aim was to replace traditional musical material with recorded (i.e. concrete) sounds which were then manipulated by FILTERing, tape reversal, TAPE LOOPs, speed changes, tape SPLICEs, or other electronic means. The source of all sounds, however, was environmental. The experimental side of this study developed the concept of l'objet sonore.
An OSCILLATION produced in an object which resonates at the same FREQUENCY, or a HARMONIC multiple thereof, as that present in a sound wave in contact with the object.
A single sound of definite, recognizable PITCH. It also refers to the SONORITY or the quality of TIMBRE of a particular sound or sounding instrument. In British musical usage the word is also employed to refer to the INTERVAL of a major SECOND.
A term used in broadcasting and recording to indicate a spatial movement of a SIGNAL. A sound is panned when it is moved smoothly from one location (e.g. LOUDSPEAKER or CHANNEL) to another. This is accomplished by using various ATTENUATORs or POTENTIOMETERs, sometimes combined into a single unit called a pan-pot or panoramic divider in order to control the AMPLITUDE of the signal in each channel.
