McGregor Boyle's piece Autumn for SATB chamber chorus and computer received its world premiere on November 19, 1999 in
Degenstein Center Theater at Susquehanna University in Selingsgrove
Pennsylvania. It was performed by the Susquehanna University Chorale,
under the direction of Peter Dennee (a Peabody alumnus) as part of their
Fall Festival concert.
Autumn is a modest piece based on a computer-generated text that Dr. Boyle
created. In performance the sound of the singer's voices are fed to the
computer, where they are processed in real time. The resulting sound envelopes
the chorus and creates a unique atmosphere, appropriate to the text and music.
On November 20, 1999, Dr. Boyle presented a lecture on some of his
compositions. His piece Nightfall: The Lookout for EWI and computer were
performed during the lecture by Kelly Boyle.
From the program notes:
The composer, MacGregor Boyle write, "Autumn is a relatively
simple piece for a small chamber chorus and digital signal processors...
The settings of the signal processors change thoughout the piece, processing
the sound of the vocal ensemble to provide an electronic "accompaniment"
... The text of Autumn was created with a computer program developed
by the computer to produce "poetry".
