CANYON VIEW 1990 A work commissioned by Yasuko Watanabe and her students. Their request: write a tune using a pentatonic (five-tone) scale, the idea being that this would be easier to improvise with as the familiar traditional Japanese music is also pentatonic. I used a different pentatonic scale for each of the three movements, each one has only one note change 1/2 step. I was still searching for a title when I had a chance to visit the Grand Canyon (Arizona. U.S.A.): each view point is quite unique though separated by a short distance, and I thought it was similar to the piece I wrote - it's all pentatonic. but go a short distance and it's a completely different view.
