Hairpins are symbols used to indicate gradual changes in volume in the score. There are two kinds: crescendo (getting louder) and decrescendo (getting quieter).
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 fine-tune the horizontal position of an end-handle (without changing playback), use the following shortcuts:
To change the height of a hairpin:
In addition to hairpins, there are cresc. _ _ _ and dim. _ _ _ lines with the same function in the Lines palette. You can adjust the text, if desired, in the Text Line Core section of the Inspector.
To turn a hairpin into its equivalent text line:
From version 3.1, a hairpin can be cut, copied and pasted just like a text element: see Summary of cut / copy / paste commands.
For versions prior to 3.1, you can only duplicate a hairpin: see Copying lines.
Properties of the hairpin can be edited in the Inspector, as follows:
Prior to version 3.1 crescendo and diminuendo lines only affected playback from one note to the next: they had no effect on the playback of a single note or a series of tied notes.
As of version 3.1, hairpins affect single notes and tied notes on instruments that support single note dynamics. For example, a piano cannot have a crescendo on a single note, but a trumpet can.
By default, hairpins will affect playback only if dynamics are used before and after the hairpin. For example, 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; if two or more crescendos are 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).
