Dear list, consider: \version "2.22.1" { d'2 \startTrillSpan b2 \startTrillSpan b1\stopTrillSpan }
Which produces: How can I bring both trills to be vertically aligned? (Compare the example in the documentation which automatically engraves a similar situation correctly: https://lilypond.org/doc/v2.22/Documentation/notation/expressive-marks-as-lines#trills). Regards, Martín.
