melac [inputfile.sem ...] [> outputfile.tac]
**semits
data and outputs a series of values representing the degree of melodic
accent associated with each note.
Melodic accent values vary between 0 (no accent)
and 1 (maximum accent).
Input is limited to only a single
**semits
data spine.
The melac command implements a model of melodic accent developed by Joseph Thomassen (see REFERENCES). Thomassen's model is sensitive to pitch contour only -- distinguishing just three types of melodic motion: ascending, descending, and unison. The model calculates tonal accent values according to a moving 3-pitch window.
It is recommended that output files produced using the melac command should be given names with the distinguishing `.mac' extension.
Options are specified in the command line.
-h displays a help screen summarizing the command syntax
**semits spine is the input, and the **melac
spine is the corresponding output.
(A **kern equivalent to **semits has been added
to increase the readability.)
