The element

Parent element:

    <harmony>

The element represents classical functional harmony with an indication like I, II, III rather than C, D, E. It represents the Roman numeral part of a functional harmony rather than the complete function itself. It has been deprecated as of MusicXML 4.0 in favor of the element.

Positive y is up and negative y is down.This attribute provides higher-resolution positioning data than the placement attribute.
