the class LyricStamper method createUnderscoreStampings.

/**
 * Creates and returns at least one {@link StaffTextStamping} containing
 * an underscore line ("___") behind the given lyric stamping
 * up to the given notehead stamping.
 * If more than one line is needed, a stamping for each line is returned.
 *
 * A list of consecutive staff stampings must be given, containing at least
 * the beginning and the ending staff of the underscore. If the underscore needs
 * only one staff, it may also be null.
 *
 * The left syllable must be given, even if it is not in the current frame.
 * The right notehead is optional. If not given, the underscore is drawn over
 * all given following staves.
