Smart playlist - only music that has not been played within the last 6 months?

[Arnie_Sherman]

How do I create a smart playlist to show only music that has not been played within the last 6 months?
I’ve only been able to figure out how to add recently played music. Looking for not played recently so I can explore stuff I’ve forgotten about.
Thanks

Click Focus>Played in the last 6 months. Then click on the plus sign to change the plus to a minus.

Perfect. I saw that plus but didn’t realize it was able to be swapped by clicking it. I kept looking for an option in the selection part of the process. I see what’s going on now.
Thanks
