Sudoku obsession

August 23, 2006

sudoku.jpgWhile I take breaks from composing, I like to do Sudoku puzzles, the 9 by 9 number placement puzzle invented by the Swiss mathematician, Leonhard Euler (1707 – 83) and named by someone in Japan, meaning “single number.” I haven’t had this much fun since I made 12-tone matrices back when I tried to be a 12-tone composer. Together with trying to pronounce these odd Hawaiian names, my Hawaiian vacation seems to be about inventing with limited numbers, or letters, or notes.
