Three Is a Magic Number was created for Schoolhouse Rock, the American educational cartoon series that used songs to teach children maths, grammar and history during the 1970s. Written and performed by jazz musician Bob Dorough, it first aired as part of Multiplication Rock in 1973 and taught the three times table through a memorable melody. It later reached a new audience when De La Soul sampled it for their 1989 song The Magic Number, helping it survive as both a teaching tool and a nostalgic pop culture reference.
