LilyPond Notation Reference: 2.8.3 Graphical notation

### 2.8.3 Graphical notation

Rhythmic items may be continued by a duration line, which gets represented by a `DurationLine` grob. Possible styles are `'beam`, `'line`, `'dashed-line`, `'dotted-line`, `'zigzag`, `'trill` and `'none`. The duration line may end with a hook (beam-style only) or an arrow.
