Synthesising Chinese flutes using Csound

Abstract

This paper gives brief descriptions of five Chinese flutes: the paixiao, xun, koudi, xiao and dizi, and short musical excerpts with their notation, idiomatic phrasing and typical ornaments. The source material section describes their spectral characteristics. Following a brief description of the previous wavetable synthesis design, an expressive new Csound additive synthesis design used to model the instruments is described. Chinese notation is a convenient Csound pitch input method using Ling Lun's tuning. Finally, several excerpts from compositions illustrate applications of the designs.
