Spatial music

Spatial music is composed music that intentionally exploits sound localization. Though present in Western music from biblical times in the form of the antiphon, as a component specific to new musical techniques the concept of spatial music (Raummusik, usually translated as "space music") was introduced as early as 1928 in Germany.

The term spatialisation is connected especially with electroacoustic music to denote the projection and localization of sound sources in physical or virtual space or sound's spatial movement in space.

The term "spatial music" indicates music in which the location and movement of sound sources is a primary compositional parameter and a central feature for the listener. It may involve a single, mobile sound source, or multiple, simultaneous, stationary or mobile sound events in different locations.

There are at least three distinct categories when plural events are treated spatially:

Examples of spatiality include more than seventy works by Giovanni Pierluigi da Palestrina (canticles, litanies, masses, Marian antiphons, psalm- and sequence-motets), the five-choir, forty- and sixty-voice Missa sopra Ecco sì beato giorno by Alessandro Striggio and the possibly related eight-choir, forty-voice motet Spem in alium by Thomas Tallis, as well as a number of other Italian—mainly Florentine—works dating between 1557 and 1601.

Notable 20th-century spatial compositions include Charles Ives's Fourth Symphony (1912–18),Rued Langgaard's Music of the Spheres (1916–18),Edgard Varèse's Poème électronique (Expo '58), Henryk Górecki's Scontri, op. 17 (1960), which unleashes a volume of sound with a "tremendous orchestra" for which the composer precisely dictates the placement of each player onstage, including fifty-two percussion instruments,'s Helicopter String Quartet (1992–93/95), which is "arguably the most extreme experiment involving the spatial motility of live performers", and Henry Brant's Ice Field, a "'spatial narrative,'" or "spatial organ concerto," awarded the 2002 Pulitzer Prize for Music, as well as most of the output after 1960 of Luigi Nono, whose late works—e.g., ... sofferte onde serene ... (1976), Al gran sole carico d'amore (1972–77), Prometeo (1984), and A Pierre: Dell’azzurro silenzio, inquietuum (1985)—explicitly reflect the spatial soundscape of his native Venice, and cannot be performed without their spatial component.
