There's no shortage of music meant for young children, but most of it is really annoying. No matter how much your kids like to listen to The Wiggles, you can only hear "Fruit Salad" so many times before you want to throw your CD out the window.
So when developmental psychologist Caspar Addyman was asked to make a song that would make babies happy, he knew it had to be something parents could enjoy as well.
With the help of music psychologist Lauren Stewart and Grammy-winning musician Imogen Heap, Addyman helped create "The Happy Song", a song specifically designed to put babies in a good mood.
The key to making this song was using what Addyman had learned about babies and their musical taste. For one thing, it had to be simple and repetitive so babies could understand it, and it's performed in major key, which sounds warm and happy.
They also let parents vote on which silly noises entertain their babies, and worked as many as possible into the song to keep things surprising. Heap even recorded her vocals with her 18-month-old daughter Scout in the room, because infants can recognize the tone we use when we talk or sing to them.
It's a great tune for parent to dance with their kids to, because it had to be upbeat to match the fact that babies have faster heart rates than adults. If you want to find out more about the making of the Happy Song, there's also a great behind-the-scenes video.
