To Buji Ismael (e-mail: 12/25-1999): The 50' and 60' composers (BOULEZ, STOCKHAUSEN, SCHAEFFER, EIMERT, BABBITT, CAGE and others) searched the eletroacustical, aleatorical and multispatial music to open new dimensions in music... Perhaps they found the METAMUSIC! And in nowadays has the Festivals of "IMPOSSIBLE MUSICS"!!! See: TRAIETTORIE SONORE/"Utopy... possible" - Vialle Varese, 71/a - 22100 - Como - Italia (fax: (39) (0) (31) 241365) And for recent tendres of the music/physics: www.ircam.fr To Bob Draper (e-mail 12/27-99): I agree with you about the limitations of human ear, but we can hear the MICROTONALS SOUNDS. Hear/Look for the compositions of: HARRY PARTCH, ALOIS HABA, WALTER SMETAK (swiss composer that lived in Bahia/Brazil and worked in Universidade Federal da Bahia), JUAN CARRILLO, NIKOLAI OBUJOV, IVAN WYSCHNEGRADSKY, JOHN APPLEBY and others.
