I’m not sure I understood your question right, but I think the usual way to do it would be to write the ”global” variable as a sequence of tempos, time signatures and other events separated by spacers or skips.
Something like: %%%%%%%%%%%%%% \version "2.23.6" global = { \time 4/4 \tempo "Allegro" 4 = 144 s1 \time 3/8 \tempo "Adagio" 8 = 76 s4. \time 5/8 \tempo "" 8 = 92 s8*5 \time 3/2 \tempo "Vivo" 2 = 152 s1. \bar "|." } part = { c'1 | d'4. | e'4~ 4. | a'1. } \new Staff << \global \part >> \layout { ragged-right = ##f } %%%%%%%%%%%%%% > 21 mars 2022 kl. 09:51 skrev Rip _Mus <ripetizioni.mus...@gmail.com>: > > Good morning, > I would need advice. > In a score with many time signature changes (where I therefore cannot use a > stable global variable of tempo and time signature), there is a way to set a > "guide" in which to set the various time signature changes, without " dirty > "the instrumental variables? > Perhaps there is some suitable context for this?
