Hi,

It seems python-ly musicxml export does not support the

\relative {c' d e f}

syntax correctly: It is pitched one octave too high.

\relative c' { c d e f }

is converted correctly to MusicXML. Maybe this is not the correct place to
report python-ly issues. But I guess one or more python-ly contributors
are reading this list?

Thanks. I have reported the issue on GitHub

Hi,

Here is another issue:

It looks like python-ly is interpreting barchecklines | as if they are
real barlines. In LilyPond this isn't true, it's just a tool to check your
lilypond sourcecode, and you can leave it out. Even if that's not
recommended practice. Consider the following example:

\version "2.19.28"
\score {
\new Staff {
\time 4/4
\relative c' {
c4 d e f g a b c |
c b a g | f e d c
}
}
\layout {}
}

When compiled using LilyPond this gives no errors, no warnings, and
correct pdf output with 4 bars, separated by 3 barlines. When using "ly
musicxml -o barchecklines.xml barchecklines.ly", if I import and view the
MusicXML file using MuseScore the first barline is missing. See
attachment.

You should probably post this to lilypo...@gnu.org as it is not specific to Frescobaldi.

this is the right list: python-ly is developed by Wilbert, etc.

Not really, you can post here. Because python-ly is developed by my
(and other Frescobaldi developers/contributors).

The musicxml export code is contributed and maintained by Peter Bjuhr,
he's on this list, so he can respond if needed.

Note that the MusicXML export is quite experimental, it depends on
parsing the LilyPond file without LilyPond, so not all musical features
(such as music constructed via Scheme) will make it to the MusicXML
output.

Best regards,
Wilbert
