The Instruments panel is a new feature in MuseScore 4. It gives you control over your instruments and some basic staff properties without having to leave the score view. All of the instruments in your score will appear in this panel.
Open the Instruments panel by clicking on the Instruments tab on the left side of the screen:
Click Add. This will open the Instruments dialog (see Choose instruments for more information).
To delete an instrument from the score, select the instrument and click the trash can icon, or press Delete.
Select any instrument and use the ↑ or ↓ buttons to change its position in the score. Alternatively, you can drag the instrument up/down using the mouse.
The visibility of entire instrument staves can be toggled by clicking the eye icon next to an instrument label.
Hidden instruments aren't ever deleted — they are simply hidden. This means they won't be printed, but you can still generate and export parts for them.
This feature might be useful if you have alternative instruments or alternative versions of a part that you'd like to toggle between (e.g. for different performers or instrumental configurations). You might also like to isolate different sections of a larger score (say, for orchestra) without actually deleting anything or generating any new project files.
Click the cog icon to expose settings for renaming your instruments. Leaving any of these fields blank will ensure that no label appears on the score or in the part for that instrument.
To replace an instrument in the Instruments panel:
The Instruments panel can also be used to add staves to an existing instrument and configure some of their basic properties.
Added staves share the same instrument but their notation can be edited independently. Amongst other things, they can be used to create staff/tablature for stringed-instrument players (e.g. guitar, banjo, ukulele etc.).
Certain notational objects on one staff can be made to automatically appear on other staves if they are linked together. Linked staves can be used to create staff/tablature for stringed-instrument players (guitar, banjo, ukulele etc.).
To create a linked staff:
Each stave contains some independently configurable properties. By clicking on the cog icon alongside a staff label (E.g. "Treble clef"), you can:

The Instruments panel can also be used to delete extra staves from an instrument:
Note: Deleting a staff from an instrument will delete the staff in the main score as well as in any part that the instrument is used.
