The <octave-shift> element
Parent element: <direction-type>
The <octave-shift> element indicates where notes are shifted up or down from their performed values because of printing difficulty. Thus a treble clef line noted with 8va will be indicated with an <octave-shift> down from the pitch data indicated in the notes.

Always empty.
Attributes
| Name | Type | Required? | Description |
|---|---|---|---|
| type | up-down-stop-continue | Yes | Indicates if this is the start, stop, or continuation of the octave shift. The start is specified as a shift up or down from their performed values |
| color | color | No | Indicates the color of an element. |
| dash-length | tenths | No | The length of dashes in a dashed line. Ignored if the corresponding line-type attribute is not dashed. |
| default-x | tenths | No | Changes the computation of the default horizontal position. The origin is changed relative to the start of the entire current measure, at either the left barline or the start of the system. 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. |
| id | ID | No | Specifies an ID that is unique to the entire document. |
| number | number-level | No | Distinguishes multiple octave shifts when they overlap in MusicXML document order. |
| 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. |
| size | positiveInteger | No | 8 indicates one octave; 15 indicates two octaves; 22 indicates 3 octaves. The default value is 8. |
| space-length | tenths | No | The length of spaces in a dashed line. Ignored if the corresponding line-type attribute is not dashed. |
