Write the words to your song first. Write the words on blank staff music paper, or open a blank staff music document in your music composition software. Use a hyphen to separate syllables in the words to your song. Each syllable will need a note of its own.
Break the syllables of your song into note counts. Like the music for your song, text should have only the appropriate number of beats per measure of music. If your song is in 4/4 time, only the words that equal four beats will be written under each measure. Write the words under the measure the accompanying music notes will be in.
Write the appropriate note on the music staff above the part of the text it refers to. If the first word of your song is "I" and it is held out for two beats (half the measure in 4/4 time), place the word "I" at the beginning of the measure and the half note (two beats) above the word. If a word is to be held out for an entire measure and continue into the next measure for a beat, write the word at the beginning of the first measure, the note of the word above it, and a curved line from the first note to the note in the next measure where the singer will continue to hold the note (and the word he is singing).
Write more than one lyric on its own measure. If there are two singers, don't try to combine both parts unless the second singer will be singing harmony on mostly the same lyrics, or if she will be singing when the other singer isn't. If the lyrics are the same but there are harmonies, you can notate the song lyrics beneath the staff and put the notes on top of one another to indicate the harmony singing.
