MuseScore's swing feature allows you to change the playback of your score from a straight to a swing rhythm. Swing can be applied globally or only to a section of the score, and is fully variable.

This inserts a System Text object which affects all staves in the system with a default swing percentage of 60%.
Edit the Swing text as required;
If you need to vary swing from the default setting, right-click the Swing text and select System text properties... Click on the "Swing Settings" tab and adjust note duration and "Swing ratio" as required.

In the "Swing Settings" section, set the desired note value and "swing ratio."
