Edit chords in Logic Pro for Mac

You can edit chords on both the Chord track and Session Player regions. You can edit the root note and chord type, add or remove chord extensions, and add a bass note other than the root of the chord. You can also choose a scale to associate with the chord to control what non-chord tones the Session Player plays—for example, in fills.

You can also edit chords by playing the chords with a connected MIDI controller, and edit them directly as text, using the same chord symbols that appear in Logic Pro.

Edit a chord

  1. In Logic Pro, do one of the following:

    • To edit a chord on the Chord track, double-click the chord.

    • To edit a region chord, double-click the chord in the Session Player Editor.

    • Control-click the chord, then choose Edit Chord from the shortcut menu.

      The Edit Chord dialog appears.

      Figure. Edit Chord dialog open showing Chord field, Root Note pop-up menu, Chord Type buttons, Chord Extension buttons, Bass Note pop-up menu, Scale pop-up menu, MIDI Input button, and Preview button.
  2. In the Edit Chord dialog, do any of the following:

    • Edit the chord name as text: Enter a new name in the Chord field.

      When the Edit Chord dialog opens, the chord name is selected in the Chord field. You can edit the chord name directly, using the same chord symbols that appear in Logic Pro. See Enter chord symbols as text.

    • Change the root note of the chord: Choose a note from the Root Note pop-up menu.

      Each chord consists of at least three notes: the root (first), third, and fifth. The root note is the one on which the chord is based, and by which it is identified. In a C major chord, the root is C; in an F# minor chord, the root is F#.

    • Change the chord type: Click one of the Chord Type buttons.

      Most commonly used chords are either major or minor, which is determined by the third of the chord. Additional types include augmented, diminished, and suspended (sus4 and sus2) chords. Suspended chords do not contain a third.

    • Add chord extensions: Click one or more of the Chord Extension buttons. To remove a chord extension, click a highlighted Chord Extension button.

      Extensions are added notes at higher intervals than the fifth. They include 7ths, 9ths, 11ths, and 13ths. Some extensions, such as b5 and #9, are chromatic to the key. Extensions modify the color or character of a chord and can also add tension.

    • Add a bass note other than the root: Choose a note from the Bass Note pop-up menu.

      Typically, the bass plays the root or fifth of the chord (except during fills), but sometimes you want the bass to play a different note, either to create a stepwise progression or to add dissonance (especially when the bass note is not a chord tone).

    • Change the scale associated with the chord: Choose a scale from the Scale pop-up menu.

      Each chord has a scale that determines which non-chord tones the Session Player can play over the chord—for example, in fills. When you add a chord, a default scale is associated with the chord, depending on the chord type and the key signature. In most cases, the default scale provides the most useful results and the least probability of unwanted dissonance.

    • Hear an example of the chord with your changes: Click the Preview button.

    Tip: While the Edit Chord dialog is open, you can move to the next chord by pressing the Tab key.

    Tip: While the Edit Chord dialog is open, you can start or stop playback of the project by pressing the Space bar.

Edit a chord using a MIDI controller

  1. Make sure the MIDI controller is connected to your Mac and is working. For more information, see Using MIDI devices.

  2. In Logic Pro, select the chord, either on the Chord track or on a region in the Session Player Editor.

    Note: On the Chord track, be sure to select a single chord, not a chord group.

  3. Control-click the chord, then choose Edit Chord from the shortcut menu.

  4. In the Edit Chord dialog, click the MIDI Input button .

  5. Play a chord on your MIDI controller.

    The selected chord changes to the chord you played.

  6. While the Edit Chord dialog is open, you can move to the next chord by pressing the Tab key.

    Note: The Edit Chord dialog must be open to edit a chord using a MIDI controller.

Enter chord symbols as text

In addition to editing chords using the buttons and menus in the Edit Chord dialog, you can edit them as text. If you are familiar with the chord symbols that appear in Logic Pro, this can be a quick way to edit chords as you work on a project.

Some common symbols include:

  • Chord name with no other symbol = major

  • m = minor

  • aug = augmented

  • dim = diminished

  • sus = suspended (2 or 4)

  • 5 = only the root and fifth, no third

  • b = flat (lowered note)

  • # = sharp (raised note)

  • / = bass note other than the chord root

  1. In Logic Pro, double-click a chord. If the chord is part of a chord group, first select the chord group, then double-click the individual chord.

    Figure. Edit Chord dialog with Chord field selected.

    The chord name is highlighted and ready for editing.

  2. Enter the chord name using your computer keyboard, using the same kinds of chord symbols that Logic Pro shows for chords.

    Tip: While the Edit Chord dialog is open, you can move to the next chord by pressing the Tab key.
