Table2. 2. Each note consists of three partials. If the sequence is played ascending, then the ?rst virtual pitch tends to be perceived, whereas if played descending, the second, lower virtual pitch tends to be heard. Only one virtual pitch is audible at a time. This can be heard in sound examples S: 6] and S: 7].

For instance, a chord played by the violin, viola, and cello of a string quartet is not usually thoughtofashavingapitch;rather, pitchisassociatedwitheachinstrumental tone separately. Thus, determining the pitch or pitches of a complex sound source requires that it ?rst be partitioned into separate perceptual entities. Only when a cluster of partials fuse into a single sound can it be assigned a pitch. When listening analytically, for instance, there may be more notes presentthaninthesamesoundwhenlisteningholistically."

O autorze

TTSS offers a unique analysis of the relationship between the structure of sound and the structure of scale and will be use to musicians and composers who use inharmonic tones and sounds. TTSS also provides a unique approach to working with environmental sounds, and there are clear applications for the use of inharmonic sounds in film scoring. The book analyses a wide range of instruments from existing instruments, electronic instruments, artificial sounds and the sounds and scales on non-western instruments, including the only such analysis of Indonesian instruments.
