"Happy Birthday to You", or simply "Happy Birthday", is a song traditionally sung to celebrate a person's birthday. According to the 1998 Guinness World Records, it is the most recognized song in the English language, followed by "For He's a Jolly Good Fellow". The song's base lyrics have been translated into at least 18 languages.[1] The melody of "Happy Birthday to You" comes from the song "Good Morning to All",[2] which has traditionally been attributed to American sisters Patty and Mildred J. Hill in 1893,[3][4] although the claim that the sisters composed the tune is disputed.[5]
The song is in the public domain in the United States and the European Union. Warner Chappell Music had previously claimed copyright on the song in the US and collected licensing fees for its use; in 2015, the copyright claim was declared invalid and Warner Chappell agreed to pay back $14 million in licensing fees.
