How a score is laid out on the page: music21’s layout objects. How a score is laid out on the page: music21’s layout objects.

A ScoreLayout gives the scaling and the page, system and staff layouts a score starts with, and stands in the score itself; a PageLayout, SystemLayout or StaffLayout stands in a measure and says how the page, system or staff changes there, or that a new page or system starts. They are read from and written to MusicXML’s <defaults>, <print> and <staff-details>. Margins and distances are in tenths of a staff space, as MusicXML gives them, kept as the integer or the decimal the file wrote.
