Hi David, In chords, all the elements have to be looped, and, as it happens, dynamics, but also scripts like staccato etc. will be among these elements and calling ledger-line-no passing anything other than a pitch will lead to the "Wrong type argument" error. Here's a quick fix (see file attached below): Filter out pitches from the elements and use the filtered list "pitches" instead of "elts". This way, only pitches will be passed to ledger-line-no, and everything will work as desired. There might be more elegant ways, but I wanted to keep the coding as original as possible. auto-ottava2.ly <http://lilypond.1069038.n5.nabble.com/file/t3887/auto-ottava2.ly> HTH, Torsten -- Sent from: http://lilypond.1069038.n5.nabble.com/User-f3.html _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
