Happy Birthday Song
The Happy Birthday song has four lines and lasts about fifteen seconds. It is in the public domain in the United States following a 2016 court ruling, so you can sing it, record it and publish the notes freely. Below are the lyrics, the letter notes for seven instruments, and full-length versions to play at a party.
Everyone knows the tune and almost nobody knows anything else about it. This is the hub for the song itself: the words, where it came from, how to play it, and what to put on when fifteen seconds is not enough.
The lyrics
Happy birthday to you Happy birthday to you Happy birthday dear [name] Happy birthday to you
That is the whole song. The third line is the only one that changes, and the only one people get wrong — the melody jumps up an octave on the first "happy" of that line, which is why crowds always fall apart there.
The copyright story
For most of a century, Warner/Chappell collected licensing fees on this song. Any film or television show that wanted a character to sing it paid, which is why restaurant chains invented their own birthday songs instead.
In 2016 a US federal court ruled the copyright claim invalid, and the song entered the public domain in the United States. That is why you now hear it in films again, and why the notes and lyrics on this site can be published freely.
How to play Happy Birthday
The melody is short, uses few notes, and is usually the first tune a beginner learns on any instrument. In C major the right-hand melody runs:
G – G – A – G – C – B, then G – G – A – G – D – C, then G – G – G – E – C – B – A, and finally F – F – E – C – D – C.
Only four chords are needed to accompany it: C, F, G and Dm.
Instrument-by-instrument guides with letter notes, tabs and chords are being added for piano, guitar, ukulele, xylophone, harmonica, violin and kalimba.
Full-length versions for a party
The traditional song is long enough for the candles and nowhere near long enough for the party. A remix keeps the melody everyone sings along to and adds a beat so the room does not fall into silence the moment the cake is cut.

Play it without ruining the moment
Nobody wants to watch you scroll through search results while a cake burns down. Set it up before guests arrive:
- Open the track on the device wired to the speaker, not on your phone
- Let it load fully, then pause at the very start
- Turn off notifications on that device
- Set the volume before the room fills up — it always sounds quieter once it does
- Have the next song queued so there is no gap
Pair the song with something they can see
Music fills the room but it does not put their name in it.
Type the birthday person's name into the free fireworks video maker and the letters explode into light one at a time. Play it on the TV while the remix runs underneath, or send it as a link that plays the moment they open it.
Common questions
Is the Happy Birthday song copyrighted? Not in the United States. A 2016 federal court ruling invalidated the copyright claim and the song is now in the public domain there. Rules vary by country.
What key is Happy Birthday in? It is most commonly played in C major or G major. C major is easiest for beginners because it uses no sharps or flats.
Why does everyone struggle with the third line? The melody jumps a full octave on that line. Untrained singers pitch the first two lines too high, which leaves no room to reach the jump.
How long is the Happy Birthday song? About fifteen seconds sung at a normal pace. Full-length remixes run four minutes or more.
What can I play instead at a party? Play the traditional version for the candles, then move straight into a remix or a party playlist so the energy does not drop.
