In LilyPond you can't reference via \fromproperty the same header field you are defining, but you can reference some other existing header field. Just use some custom name (e.g. "mytitle") for the shared title definition and reference that in the markup.
An alternative approach to title style customization would be redefining bookTitleMarkup https://lilypond.org/doc/v2.23/Documentation/notation/custom-titles-headers-and-footers#custom-layout-for-titles Regards, Jakub ne 31. 5. 2026 v 17:20 odesílatel Michael Scheer <[email protected]> napsal: > Hi Lilypond users, > > I access a pieces global header via an include, it is accessed from > different files. > > Now in the full score, I need bigger headers.
