4 years ago This is an alternate method of notating trills. This region is also incorrect in a MuseScore import of the MusicXML file:
Looking at the first trill in MusicXML:
<note>
<pitch>
<step>B</step>
<alter>-1</alter>
<octave>3</octave>
</pitch>
<duration>768</duration>
<voice>1</voice>
<type>quarter</type>
<accidental>flat</accidental>
<stem>up</stem>
<notations>
<ornaments>
<trill-mark default-y='14'/>
<wavy-line type='start' number='1'/>
<wavy-line type='stop' number='1'/>
</ornaments>
</notations>
</note>
<note>
<pitch>
<step>B</step>
<alter>-1</alter>
<octave>3</octave>
</pitch>
<duration>1536</duration>
<voice>1</voice>
<type>half</type>
<accidental>flat</accidental>
<stem>up</stem>
</note>
<backup>
<duration>1536</duration>
</backup>
<note>
<grace slash='no'/>
<pitch>
<step>C</step>
<octave>4</octave>
</pitch>
<voice>3</voice>
<type>eighth</type>
<accidental>natural</accidental>
<stem>up</stem>
</note>The trill noted is given without the auxiliary note, then the note after the trilled note, then there is a backup command and the auxiliary note is added as a grate note in a separate voice.
This should be fixed in the Sibelius file: Use the standard auxiliary note system. Alternatively this can be fixed by hand in Humdrum.
Trill notation is missing wavy line, note trilled to is not in brackets, implying grace note? Berg 443 - R443_Ber-w10p321m593-595
