Know which format you have
MusicXML describes notation as structured musical data. A PDF or photograph describes how the page looks and must go through recognition instead. A MIDI file describes performance events and is not accepted by the MusicXML file picker. Renaming a PDF or MIDI extension to XML does not convert its contents.
Export from notation software
Use the MusicXML export option in your notation editor. TuneViva accepts .musicxml, .xml and compressed .mxl files containing a partwise score. Keep the original project file in your editor as well: an interchange export is a separate copy, and layout or playback details can differ between applications.
Open the score in practice
On the practice starting page, choose Open MusicXML and select your export. TuneViva reads the file, checks that it contains supported notation and opens the practice workspace. Use a file smaller than two megabytes. For a compressed MXL file, the expanded score must also fit the limit.
Check the imported notation
Before practicing, compare the opening bars with the source score. Check the part names, clefs, note durations and any repeats or unusual notation. Listen to a short passage. Choose one staff if that helps, but remember that the hand controls select upper and lower staves rather than analysing a pianist’s fingering.
Keep a copy of your music
The imported file stays in the browser rather than being uploaded. The temporary practice copy uses browser session storage, so keep your own MusicXML file for later sessions. Do not treat a temporary practice link as a saved online score or a reliable way to share the file with another person.
Fix an import error
If the file is too large, export a shorter passage or fewer parts from your notation editor. If TuneViva reports an unsupported score, export partwise MusicXML again instead of renaming the file. If browser storage is unavailable, allow session storage or try a smaller export. For a PDF or photo, use Scan rather than Open MusicXML.
