This 15-second clip is going viral for some reason. 
 
It’s entitled When Mama isn’t Home and shows a father and son making sweet music in the kitchen. 
 
Dad’s on the trombone and his kid is on the…oven door. 
 
The ditty kicks off with a short solo from trombone man before he’s joined by aggressive door slamming. 
 
The combination is beautiful. But it’s the kid’s head-banging which has really made this video an internet sensation.
