Choose a cheerful melody in a major key
Keep the rhythm simple and easy to sing
Write a catchy, repetitive chorus
Use warm, celebratory words
Mention the person’s name in the lyrics
Include birthday themes like cake, candles, wishes, and joy
Keep the song short and memorable
Add a fun hook that repeats
Make the melody easy for all ages to sing
Use uplifting chords and a bright tempo
Sing with energy and a happy tone
Test the song by singing it aloud
Revise any lines that feel awkward or hard to remember
