the space that a regular notehead takes up. However, this needs to be adjusted for upstems. This applies to all non-standard noteheads shapes, and is already implemented for grace notes and cue notes:</p> <img width="288" alt="Screen Shot 2022-06-03 at 8 58 19 AM" src="https://user-images.githubusercontent.com/3487289/171902182-cf774967-4e07-4bd6-9b0d-3282c7837ae8.png"> <details> <summary> Click to view MEI data for above example </summary> ```xml <?xml version="1.0" encoding="UTF-8"?> <?xml-model href="https://music-encoding.org/schema/dev/mei-all.rng" type="application/xml" schematypens="http://relaxng.org/ns/structure/1.0"?> <?xml-model href="https://music-encoding.org/schema/dev/mei-all.rng" type="application/xml" schematypens="http://purl.oclc.org/dsdl/schematron"?> <mei xmlns="http://www.music-encoding.org/ns/mei" meiversion="5.0.0-dev"> <meiHead> <fileDesc> <titleStmt> <title /> </titleStmt> <pubStmt /> </fileDesc> <encodingDesc> <appInfo> <application isodate="2022-06-03T08:55:22" version="3.11.0-dev-fa769a1"> <name>Verovio</name> <p>Transcoded from Humdrum</p> </application> </appInfo> </encodingDesc> <workList> <work> <title /> </work> </workList> </meiHead> <music> <body> <mdiv xml:id="m2hl4yg"> <score xml:id="sn0bqj5"> <scoreDef xml:id="swb95me"> <staffGrp xml:id="so72gte"> <staffDef xml:id="staffdef-L1F1" n="1" lines="5"> <clef xml:id="cmmb6e8" shape="G" line="2" /> </staffDef> </staffGrp> </scoreDef> <section xml:id="section-L1F1"> <measure xml:id="measure-L1"> <staff xml:id="staff-L1F1" n="1"> <layer xml:id="layer-L1F1N1" n="1"> <chord xml:id="chord-L2F1" dur="4"> <note xml:id="note-L2F1S1" oct="4" pname="c" accid.ges="n" /> <note xml:id="note-L2F1S2" oct="4" pname="e" accid.ges="n" cue="true"/> <note xml:id="note-L2F1S3" oct="4" pname="g" accid.ges="n" /> </chord> <chord xml:id="chord-L3F1" type="placed" dur="4" stem.dir="down"> <note xml:id="note-L3F1S1" oct="4" pname="c" accid.ges="n" /> <note xml:id="note-L3F1S2" oct="4" pname="e" accid.ges="n" cue="true" /> <note xml:id="note-L3F1S3" oct="4" pname="g" accid.ges="n" /> </chord> </layer> </staff> </measure> </section> </score> </mdiv> </body> </music> </mei> ``` </details> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/rettinghaus"><img src="https://avatars.githubusercontent.com/u/7693447?v=4" />rettinghaus</a> commented <strong> 2 years ago</strong> </div> <div class="markdown-body"> <p>I'm wondering what should happen in chords <em>without</em> stem.
