Période

1964-1971

Canada

These rolls were used by Istvan Anhalt, a composer and founding director of the McGill Electronic Music Studio to records electronic music scores read by the Le Caine Spectrogram (1986.0006). The spectrogram was an unique instrument designed by pioneering Canadian electronic music composer & instrument designer Dr. Hugh Le Caine (1914-1977) of the National Research Council of Canada, and built at NRC's Elmus Lab. In 1964 it was sent to the newly opened electronic music studio at McGill University, the second such facility in Canada.

Fonction

A length of graph paper upon which is inscribed an electronic musical score intended to be read and played by an electronic musical instrument, the spectrogram.

Technique

An example of an electronic musical score used to program a 24-channel photo-electric Spectrogram designed by Hugh Le Caine. Like Le Caine's 1952 Coded Music Apparatus, the Spectrogram used long pieces of moving chart paper inscribed by the composer. The music was recorded by covering parts of the chart paper with black marker; the paper was moved through the Spectrogram's optical reading device, which converted the composer's inscription to electronic impulses, generating electronic music sounds. The Spectrogram was a one-of-a-kind instrument which functioned essentially as a multiple voltage generator or programmable mixer which could be used to control a variety of sound sources.
