about

Christopher Hobbs, Sudoku Collection 2020

So far I have made 138 pieces with the title Sudoku. Nearly all of them use Apple’s GarageBand software for their sound sources and realization. Some of them have already been issued; a double CD by the EMC in 2006 (EMC 104), Sudoku 82 in a live realization by Cold Blue in 2009 and Sudoku 104 as an EMC single download (EMC 105) This set dates from 2007-2010. I have chosen them to run together (hence the inclusion of Sudoku 104 which I think makes a suitable introduction to the set) though obviously they were not made with that in mind. In common with my other Sudoku pieces I chose the building blocks of the pieces; the sound-world, the choice of loops, the duration. Other aspects of the music – the repetition of loops, their positioning in the overall structure, dynamic changes – were chosen using random means derived from hexadecimal Sudoku grids. Notes on individual pieces follow.

Sudoku 104 (2009): GarageBand includes a few spoken words, and these were incorporated into the piece. The word “attention” at the start is entirely fortuitous, as is the appearance of a hitherto-unused loop right at the end of the piece.

Sudoku 78 (2008): In this piece there are eight tracks of organ sound, each using a low C as a drone, each track then having a different higher note to form the scale C D E F# G A Bb C. The tracks are constantly on the move as far as dynamics are concerned; each reaches a point of maximum volume on four occasions, marked by a glockenspiel note to reinforce the point.

Sudoku 58 (2007): A homage to the Swiss sculptor Jean Tinguely and his kinetic art-works.

Sudoku 133 (2010): Otherworldly sounds. Almost alone among the Sudokus, this one was made using Logic Pro.

Sudoku 120 (2009): Made using “Space vibes” sounds

Sudoku 51 (2007): A mix of organs and dreamy guitars.
