    Naturals on key signature changes

    By default, MuseScore only shows cancelling naturals when the key signature changes to that of C Major/A minor (no sharps or flats). In all other cases, it simply shows the new key signature without cancellations:

    Default key signature changes

    However, you can opt to display cancelling naturals for all key signature changes:

    1. From the menu, select StyleGeneral...Accidentals. You'll see the options:

      Dialog: Style / General... / Accidentals

    2. Select one of the three options.

    3. If you are in a part and want the new option to apply to all parts, click on Apply to all parts.
    4. Click OK to exit.

    For example, selecting the option "Before key signature if changing to fewer ♯ or ♭" gives:

    Naturals before key signature

    And the option "After key signature if changing to fewer ♯ or ♭. Before if changing between ♯ and ♭" gives:

    Naturals before and after key signature

    Key signature changes and multi-measure rests

    Multi-measure rests are interrupted if there is change of key signature:

    Example with multi-measure rests

    Courtesy key signatures

    To turn off the display of a particular courtesy key signature:

    • Select the relevant key signature and untick "Show courtesy" in the "Key Signature" section of the Inspector.

    To turn off the display of all courtesy key signatures:

    • From the menu, select StyleGeneral...Page, and untick "Create courtesy key signatures."

    Note: Courtesy key signatures are not displayed at section breaks.

    Custom key signatures

    To create a custom key signature:

    1. Press Shift+K to display the Key signatures section of the Master palette.

      Master Palette: Key signatures

    2. In the Create Key signature panel, drag accidentals from the palette onto the "staff" above to create the desired key signature. Use the Clear button, if required, to remove all accidentals from the "staff."

    3. Press Add to move the new key signature into the library (center panel).

    Note: Playback of custom key signatures is not currently supported.

    To move a key signature from the Master palette to a custom palette:

    • Drag and drop the key signature onto a palette.

    To apply a key signatures to the score directly from the Master palette, use one of the following methods:

    • Select a measure and double-click a key signature in the Master palette.
    • Drag a key signature from the Master palette onto a measure.
