In your chords, you use a comma (,) instead of a dot (.) and you use more than one colon (:) which is not the correct syntax. You can write this: \new Staff \chordmode { f2:dim3.5.8/+c } The pattern is (and almost every part can be omitted): <root note> <duration> : <modification> <additions and removals> / or /+ <base> https://lilypond.org/doc/v2.20/Documentation/notation/chord-mode I also send you the part about chords from my LilyPond cheat sheet: http://joramberger.de/files/lilypond_sheet_2.18_en.pdf Cheers, Joram
