Dissonance

REPRESENTATION

diss — sensory dissonance representation

DESCRIPTION

The diss representation is used to characterize the degree of sensory dissonance for successive acoustic moments. Two types of tokens are recognized by **diss: dissonance-tokens and barlines. Dissonance-tokens encode integer values greater than or equal to zero. Larger values represent higher sensory dissonance. Dissonance values reflect the measurement method devised by Kameoka and Kuriyagawa (see REFERENCES).

Barlines are represented using the "common system" for barlines — see barlines.

FILE TYPE

It is recommended that files containing predominantly diss data should be given names with the distinguishing `.dis' extension.

SIGNIFIERS

The following table summarizes the diss mappings of signifiers and signifieds.

----- ------------------------------------------
0-9   dissonance values specified as integers;
measure numbers
=     barline
==    double barline
=;    barline with pause sign
