Hairpins are line objects. To create a hairpin:
Alternatively, use one of the following options:
Double-click on the hairpin to enter edit mode. Then click on the end handle that you want to move:
Use one of the following shortcuts:
This method of extending or shortening the hairpin maintains playback integrity and allows it to cross line breaks:
To change the position of an end handle without changing the position of its anchor, use the following shortcuts:
Note: The commands listed in step 3 are only used to tweak the final appearance of the hairpin (e.g. see image below): they do not change its playback extent nor do they allow it to cross line breaks. If you want the latter, use the Shift+→ or Shift+← commands instead (step 2).
Note: The "Reset" command (Ctrl+R (Mac: Cmd+R)) will undo these small adjustments, but will not undo anchor changes.
In addition to hairpins, there are cresc. _ _ _ and dim. _ _ _ lines with the same function in the Lines palette. To change the text (e.g. to cresc. poco a poco, or decresc. instead of dim), right-click on the line and choose Line Properties....
To turn a hairpin into its equivalent text line:
Playback of crescendos and diminuendos is only effective from one note to the next; it currently is not possible to change the dynamic over the course of a single note (and tied notes count as single notes here). By default, hairpins will affect playback only if dynamics are used before and after the hairpin.
For instance, a crescendo spanning notes between p and f dynamics will cause a dynamic change on playback. However, between any two successive dynamics only the first appropriate hairpin will have effect: a diminuendo between p and f will be ignored; of two or more crescendos between p and f, all but the first will be ignored.
A hairpin may be used without dynamic marks, by adjusting "Velocity change" in the Inspector (values in the range 0 to 127).
