Closing Songs Closing a Song To close a Song, hold down [Ctrl](Win) or [Cmd](Mac) and press [W], or select “Close” from the File menu. Alternatively, click the close button in the upper corner of the Song document window. If you have unsaved changes, you will be asked if you want to save the song before closing. Note that when you’re closing the last open Song document in the Windows version of Reason Essentials, the application will quit.
