A Kansas farmer has gone viral.
He's getting calls from media around the world -- and even a re-tweet from Ellen DeGeneres.
That's Derek Klingenberg -- playing the song "Royals" by New Zealand pop star Lorde, on his trombone.
The audience -- you may have noticed -- is Derek’s herd of cattle.
On his Facebook page, the talented rancher says he frequently plays trombone for his cattle, to calm them and make it easier to round them up.
If you listen closely, you'll even hear the cattle mooing along and responding to the notes!
He also throws in treats to keep the livestock happy.
