The problem is there is a "." character whose significance eludes me. The guile reference doesn't index this character, and I can only find references to it in writing literal pairs. But I'm sure someone experienced would recognize what this could be (the dot occurs on the eleventh line): (define (ignatzek-format-exception root exception-markup bass-pitch lowercase-root?) (make-line-markup `( ,(name-root root lowercase-root?) ,exception-markup . ,(if (ly:pitch? bass-pitch) (list (ly:context-property context 'slashChordSeparator) (name-note bass-pitch #f)) '())))) Richard Shann
