Slurs can curve upwards, downwards, or have a multi-segment S-shape. Dorico Pro automatically determines the appropriate curvature direction for slurs based on the notes within their ranges, but you can change the curvature direction of slurs manually.
A slur on a single staff always curves upwards and is placed above the notes, unless all of the notes under the slur are up-stem, in which case it curves downwards and is placed below the notes. If a slur applies to a mixture of up-stem and down-stem notes, it is placed above the staff and curves upwards.
The following options for slur curvature direction are available when you activate Direction in the Slurs group of the Properties panel:
- Up
-
Forces slurs to curve upwards, and appear above notes.
- Down
-
Forces slurs to curve downwards, and appear below notes.
- Up/Down
-
Forces slurs to comprise two segments: the first curves upwards, the second curves downwards to create a mirrored S-shape. It is typically used when phrases start in the lower staff and end in the upper staff; for example, in piano parts.
- Down/Up
-

You can set your preference for whether slurs follow the stem direction, or always appear above notes, on the Slurs page in Engraving Options.
-
You can adjust the precise shapes of individual slurs, and each slur segment, in Engrave mode using the square handles on each slur.

In jazz scores, slurs are sometimes treated as an articulation, so positioning all slurs above the staff is preferred.
