A slur is a curved line between two or more notes indicating that they are to be played legato—smoothly and without separation. Not to be confused with Ties, which join two notes of the same pitch.
There are a number of ways to add a slur to a score, and all may be useful depending on the context (adding a slur from the lines palette is also possible but not recommended).
Make sure you are not in note input mode and select the first note that you want the slur to cover:
Press S to add a slur extending to the next note:
(Optional) Hold Shift and press → (right arrow key) to extend the slur to the next note. Repeat as required:
(Optional) Press X to flip the slur direction:
Press Esc to exit edit mode:
If you only want to adjust the position of a slur:
To adjust all the properties of a slur (length, shape and position):
Note: The two outer handles adjust the start and end of the slur, whilst the three handles on the curve adjust the contour. The middle handle on the straight line is used to move the whole slur up/down/left/right.
A slur can span several systems and pages. The start and end of a slur is anchored to a note/chord or rest. If the notes are repositioned due to changes in the layout, stretch or style, the slur also moves and adjusts in size.
This example shows a slur spanning from the bass to the treble clef. Using the mouse, select the first note of the slur, hold down Ctrl (Mac: ⌘) and select the last note for the slur, and press S to add the slur.
X flips the direction of a selected slur.
Dotted slurs are sometimes used in songs where the presence of a slur varies between stanzas. Dotted slurs are also used to indicate an editor's suggestion (as opposed to the composer's original markings). To change an existing slur into a dotted or dashed slur, select it and then in Inspector (F8) change
