720 Chapter 33 Working With Notation
Note: Ensure that you insert chord symbols at the correct bar position. Watch the help
tag while inserting the chord object.
2 Enter the text for the chord.
A chord symbol can include a root note, a separate bass note, and two lines of
extensions. As you enter the text for the chord in the Score Editor, you can influence
the way the inserted text is distributed:
 First, enter the root, then the extensions, then—after typing a slash—the (optional)
additional bass note.
 As soon as you enter a number, everything following it will be placed in the upper
extension line. If you write “G7(b9/b13)”, the whole “7(b9/b13)” will be placed in the
upper line, and the lower line remains blank.
 If you write letters before a number (FMAJ7/9, for example), Logic Pro places the
letters in the lower line, and everything after the first number, in the upper line.
 You can influence this automatic placement by entering a comma in the text:
everything before the comma will be placed in the lower line, and everything after it,
into the upper line. Only one comma can be used. Blank spaces can be entered, to
create additional horizontal space between the extension and the root.
To edit a chord symbol, do one of the following:
m Double-click on the root, then edit the chord symbol in the Chord Symbol window.
There are four entry fields for the different parts: one for the root, one for an additional
bass note, and two for extensions—which are placed above each other.
