Create MIDI files from Lilypond snippet - midi

Question

This is not a duplicate question on how to create a MIDI file from Lilypond. I have done that many times.
I have created some lilypond snippets, and I want to extract MIDI from them. Normally I would do that in the \score block like this:
\score {
\music
\layout { }
\midi { }
}
But, my snippet does not contain a \score block; it is written like this:
\version "2.18.2"
\include "lilypond-book-preamble.ly"
\paper {
indent = 2\mm
line-width = 210\mm
}
\layout {
indent = #0
\context {
\Score
\remove "Bar_number_engraver"
}
}
\relative c'
{
\tempo 4 = 60
\clef treble \key d \major g8^\markup { C } g8 b4 b8 b8 d4 cis8 cis8 e4 b8 b8 d4
}
This code creates a perfect PDF snippet. But I don't know where to put the \midi { } block to create a MIDI file.

Answer 1

I think the easiest solution is to assign your music to a variable and create a \score block. Is there a reason why you are avoiding to use a \score block in your example? For instance, the code below generates both MIDI and pdf files:
\version "2.18.2"
\include "lilypond-book-preamble.ly"
\paper {
indent = 2\mm
line-width = 210\mm
}
\layout {
indent = #0
\context {
\Score
\remove "Bar_number_engraver"
}
}
music = \relative c'
{
\tempo 4 = 60
\clef treble \key d \major g8^\markup { C } g8 b4 b8 b8 d4 cis8 cis8 e4 b8 b8 d4
}
\score{
\music
\layout{}
\midi{}
}
