Hi Gian Paolo, > how to write a score without time signature and bars placed on request?
Just remove the Time_signature_engraver: \version "2.25.11" \language "english" \layout { indent = 0 ragged-right = ##f \context { \Staff \remove Time_signature_engraver } } { \key d \major \time 5/2 d'2 d' cs' d'1 \time 7/2 b2 d' d' d' cs' d'1 \time 9/2 b2 d' d' d' d' e'1 ~ 1 } > I read the manual but didn't find a solution. https://lilypond.org/doc/v2.23/Documentation/notation/visibility-of-objects#removing-the-stencil That should have led you to the equivalent solution: \version "2.25.11" \language "english" \layout { indent = 0 ragged-right = ##f } { \omit Staff.TimeSignature \key d \major \time 5/2 d'2 d' cs' d'1 \time 7/2 b2 d' d' d' cs' d'1 \time 9/2 b2 d' d' d' d' e'1 ~ 1 } Hope that helps, Kieren. ______________________________________________ My work day may look different than your work day.
