MuseScore 4 automatically creates a separate (default) part for every instrument in your score.
To open all parts at once:
To open an individual part:
You can also select specific parts to open at once. Do this by holding Control (Mac: ⌘) while selecting the parts you’d like to open, then click Open selected. You can also select a range of contiguous parts by clicking the first and holding Shift while clicking the last.
Click the X close button in a part tab to close a part.
Note that changes you make to a part will be saved with that part and retrievable the next time you open it from the Parts dialog.
The Parts dialog is tightly integrated with the new Instruments panel. This integration makes it easy for you to create parts with any combination of instruments from your score.
There are two ways to customize parts in MuseScore 4: using the default (i.e. ready-made) parts to reveal other instruments, and creating entirely new parts.
As we’ve already seen, MuseScore 4 automatically creates a new (default) part for every instrument in your score. All you have to do is open the part from the Parts dialog.
In fact, each default part already contains all of the instruments in your score – they’re simply hidden from view (except, of course, the chosen part instrument).
This means you can “reveal” other instruments within any of the default parts. To do this:
This instrument will now be visible in the chosen part.
This makes creating custom parts an incredibly flexible process. Revealing or hiding other instruments is completely non-destructive, meaning you can customize every instrument in every part, and hide or show only what you want to reveal to different players (or for different musical projects) without having to create entirely new parts each time.
MuseScore 4 does of course give you the option to create a completely "blank" part from scratch, allowing you complete customization control. To do this:
Your new part will now be open in the Score tab, but it will appear to contain no instruments. To add instruments to this part:
Sometimes it will be necessary to create individual parts from staves that contain multiple voices. You might, for example, want to extract separate parts for orchestral players who share a staff in the main score (E.g. Flute I and Flute II). Or you might wish to create individual vocal parts from choral scores where, for example, four voices are notated across two staves.
You'll need to first create (see above) or duplicate (see below) a part. To then select which voices will appear in a part:
Style settings for a wide range of engraving elements can be applied specifically to parts without affecting the main score.
To change style settings for a specific part:
Changes you make in this dialog will affect only the part selected in the Score tab. If you want changes to affect all parts (but not the main score), select Apply to all parts before clicking OK.
Learn more about saving and loading default style settings in Templates and styles.
This all takes place in the Parts dialog (accessible from the Parts button in the toolbar).
Simply click the "three dots" menu icon next to a selected part to reveal its options. Note that only newly created parts (created by clicking the Create new part button) can be deleted. All parts can be duplicated or renamed.
To duplicate any part:
To rename any part:
Note you can also double click on any part in the Parts dialog to rename it.
To delete a newly created part:
When a part is deleted, its tab in the Score tab (if already opened) will be closed. Any customizations made to that part will also be lost. The part will also no longer appear in the Parts dialog.
To export parts:
Parts will be exported in the PDF format by default. To change the export format, select your preferred format from the dropdown menu in Export settings. You can export your parts in a range of image and audio formats, as well as the braille format for compatible printers. For more information, see File Export.
To print parts:
Note that parts can currently only be printed one at a time.
