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.

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.
