# The <function> element


Parent element:
    
        
        <harmony>


The <function> 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 <numeral> element.

## Attributes

| Name | Type | Required? | Description |

| default-x | tenths | No | Changes the computation of the default horizontal position. The origin is changed relative to the left-hand side of the note or the musical position within the bar. Positive x is right and negative x is left.This attribute provides higher-resolution positioning data than the <offset> element. Applications reading a MusicXML file that can understand both features should generally rely on this attribute for its greater accuracy. |
| default-y | tenths | No | Changes the computation of the default vertical position. The origin is changed relative to the top line of the staff. Positive y is up and negative y is down.This attribute provides higher-resolution positioning data than the placement attribute. Applications reading a MusicXML file that can understand both attributes should generally rely on this attribute for its greater accuracy. |
| font-family | font-family | No | A comma-separated list of font names. |
| font-size | font-size | No | One of the CSS sizes or a numeric point size. |
| font-style | font-style | No | Normal or italic style. |
| font-weight | font-weight | No | Normal or bold weight. |
| relative-x | tenths | No | Changes the horizontal position relative to the default position, either as computed by the individual program, or as overridden by the default-x attribute.  Positive x is right and negative x is left. It should be interpreted in the context of the <offset> element or directive attribute if those are present. |
| relative-y | tenths | No | Changes the vertical position relative to the default position, either as computed by the individual program, or as overridden by the default-y attribute. Positive y is up and negative y is down. It should be interpreted in the context of the placement attribute if that is present. |
