Electro-Acoustic

Electro-acoustic music includes several different sonic and musical genres or musical techniques. All electro-acoustic music is made with electronic technology. Many works in the field are concerned with those aspects of sonic design which remain inaccessible to either traditional or electronic musical instruments played live.

Some electro-acoustic compositions make use of sounds not available to typical acoustic instruments, such as those used in a traditional orchestra. These sound sources may be pre-recorded sounds, transformed sound recordings or synthesized timbres. Some electro-acoustic music places less emphasis on the “traditional” concerns of score-based music — rhythm, metre, harmony and melody, and instead tends to explore the interplay of gesture and texture. This interaction between sounds and the ways they are transfigured over time has been termed "spectromorphology" by the composer Denis Smalley in 1997.

Electro-acoustic compositions can also utilise the manipulation of sound in space, using various loudspeaker-based spatialisation techniques.
