Home In 1958 "the Electronic Poem" Edgara Vareza were tested spatial possibilities of 400 loudspeakers in firm "Филипс" pavilion at the Bruxelles exhibition. By sixtieth years numerous experiments which have led to the conclusion about space functions at it "озвучании" have been spent also. On the basis of these ideas there were also new forms of concert halls - such as "the Hall of Century", constructed under Frankfurt, with вариабельно the established scene, full звукопоглащением all walls and possibility of artificial acoustics; "the New Berlin Philharmonic society", appeared valuable experimental object not only for spatial music of the electronic nature, but also for spatially differentiated tool music. So I.S.Bach some products with distribution of voices on четырeм to platforms there have been executed and thus it was unexpectedly found out, how it is easy to watch the polyphonic invoice when voices чeтко are distributed on all premise. Orchestral players by means of small control loudspeakers and telescreens have been well synchronised on дирижeра so the big distance between orchestral groups - to 20 metres - has not made difficulties.
