Representation: **diss¶
Humdrum Representation for 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.

EXAMPLES¶
A sample document is given below:
**diss *C: *M4/4 =1 65 84 152 160 =2 211 1017 841 1221 =3 *- Note that rests are not represented in the **diss scheme.
PERTINENT COMMANDS¶
The following Humdrum command produces **diss data as output:
**diss** calculate the degree of sensory dissonance for successive spectra
