The synco filter marks syncopated notes in a score.
Options
Basic usage
A syncopation is defined as a note that is longer than the metric level on which it starts. For example a whole note in 2/1 that starts on the second half-note of the measure is synocpated since it is starting on a half-note level in the metric cycle, but it has a whole-note duration.
Currently the tool only works on music with a whole-note beat (i.e., Renaissance music).
Highlight color
The -c option can be used to set the highlight color of syncopations
(any SVG color).
Summary statistics
The -i option will show information about one or more input files, such as:
120 888 13.51%
180 1344 13.39%
117 881 13.28%
106 799 13.27%
148 1117 13.25%
190 1436 13.23%
309 2339 13.21%
203 1537 13.21%
80 610 13.11%
104 793 13.11%
The first number on a line is the number of syncopation notes in the file, the second number is the number of notes in the file, and the third number is the syncopation density (the fraction of notes in the score which are synopated).
When not using the -i option, the marked-up scores also include this information
in added reference records, such as:
!!!syncopated_notes: 33
!!!total_notes: 375
!!!syncopated_density: 8.8%
Add filename to summary statistics
The -f option adds the filename to each summary statistics line:
