Program notes
This piece was originally written to be played on a mbira, which is an African instrument consisting of metal tines attached to a gourd or box resonator. Since construction varies between instruments, the selection and tuning of pitches is unique for each instrument. “Walking Music” was composed for a particular instrument, and is therefore bound by a limited collection of pitches, progressing by gradually exploring this vocabulary. The surface rhythms of the work explore the interrelations between simple polyrhythms, while the large-scale structure uses additive processes to develop metrical groupings.
