Canticum

Canticum is a piece for bowed guitar and computer improviser. This piece is of indeterminate length, decided in the moment by the performer as they react to the sound generated by the computer improviser. The computer improviser software has been trained with recordings of bowed guitar in a wide variety of tunings, which it draws from to generate an accompaniment for the live guitar.

The acoustic guitar is tuned from a low B in just intonation ratios: 1/1 - 3/2 - 9/4 - 3/1 - 7/2 - 4/1.

Premiere: Taylor Brook, Phillip T. Young Hall, University of Victoria, February 12, 2023.
