Python/LilyPond

In developing the page "Beat (acoustics)" on Wikiversity I needed to find a LilyPond instrument that had no vibrato, and this required quick access to all LilyPond's 128 different imitations of a musical instrument. This short code wrote so much wikitext so long I had to upload it to Wikiversity in short segments.

The list of instruments in #instruments.txt shown below was copy/pasted from:

• https://lilypond.org/doc/v2.23/Documentation/notation/midi-instruments

The output wikitext can be found by viewing the source of the Wikiversity page at:

• Music/Software/Lilypond/MIDI

Code

##Sample riff:
##====recorder====
##<score sound="1"> \relative c'' {\set Staff.midiInstrument = #"recorder" \clef treble \cadenzaOn  c2\grace { b16[c] } [b g e (b'] a1) } </score>
##<score sound="1"> \relative c''' {\set Staff.midiInstrument = #"recorder" \clef treble \cadenzaOn  c2\grace { b16[c] } [b g e (b'] a1) } </score>
##<score sound="1">\relative c' { \set Staff.midiInstrument = #"recorder" \clef bass \cadenzaOn  c2\grace { b16[c] } [b g e (b'] a1) } </score>

## Open instruments.txt to create ilist, which lists all LilyPond instruments:
ilist=[]
with open("instruments.txt", "r") as infile:
    for line in infile:
        ilist.append(line.rstrip())
## Each riff is different in one of three ways:        
prime=["''","'''","'"]
clef=[r'\clef treble', r'\clef treble', r'\clef bass']
finish=r"\cadenzaOn  c2\grace { b16[c] } [b g e (b'] a1~a2) } </score>"

## Open an output file and write the entire passage, line by line:
with open("wikitext.txt","w") as outfile:
    for i in range(len(ilist)):
        outfile.write("\n===="+ilist[i]+"====\n")#                         ====recorder====
        for j in range(3):
            outfile.write('<score sound="1"> \\relative c'+prime[j])#      <score sound="1"> \relative c'''
            outfile.write(r'{\set Staff.midiInstrument = #"'+ilist[i]+'"')# {\set Staff.midiInstrument = #"recorder"
            outfile.write(clef[j]+finish)
            outfile.write("\n")
