Recording of Paul Pedersen's Fantasie. This 8 minute, 2-track tape piece was composed in 1967 at the Mc Gill University electronic Music Studio. The work was conceived as a multimedia presentation using 3 projectors with hand painted slides by the Montreal artist Gino Bielanski. The piece is in 15 sections, which are synchronized with the fifteen slides used in the centre projector. Pitch organization in the work is centered on a 9 pitch series between 77 and 2335 Hz with successive pitches 200 Mels apart. Two sections involve the use of the Shephard Scale. The basic sound sources used are limited to white noise, sine and square waves. Much of the synthesis of the work was done using the channel Spectrogram developed by Dr. Hugh Le Caine of the National Research Council of Canada.
