If you need to make a symbol larger without affecting the size of the rest of the music, how do you do it? The answer lies in the House Style > Edit Symbols dialog. In the picture above, the comma symbol often used as a breath mark is shown in four sizes. Here’s how to do it.
First, choose House Style > Edit Symbols and find the symbol you want to enlarge. The comma is on the third row labeled Articulation, about a fifth of the way down the list:
Music font doesn’t in fact refer directly to a font, but rather to a text style which defines the font from which the symbol is taken. Number refers to the character number of the glyph in question from the font defined by the text style. Click Cancel or OK to close this dialog.
In order to make the symbol larger, you must define a new text style with the necessary font set to a larger point size. Click the Music Fonts button, and select the text style upon which you want to base your new text style: in the case of the comma symbol, it’s Common symbols. Click New.
Now scroll to the bottom of the list of symbols, to the row of empty slots labeled User-defined. Select the first empty slot in the row and click Edit. In the dialog that appears, choose your new text style from the Music font drop-down, type the appropriate glyph number into the Number control, and if you like give your new symbol a name:
Finally, click OK to confirm these changes, and then Close to close the Edit Symbols dialog. Your new larger symbol is now available for creation in your score at the bottom of the Create > Symbol dialog, and you can take this symbol into other scores, either by exporting the house style from this score and importing it into others, or simply by copying and pasting the symbol from this score to another.
