Yasser’s book A Theory
of Evolving Tonality (1932) made a great impression on me when I started researching microtonality in the early 1990s. It’s not so much the conclusions he came to, but more an appreciation of his journey which I found inspiring and insightful. My short piece ‘evolves’ using conventional melodic techniques but also punctuates the melody with figures which outline harmonies.
