 The song is sung from a first person viewpoint , allowing an audience to " internalize " the message — which involves everybody — by singing the word " we " together . " Send It On " commences with acoustic guitars and then transitioning to violins . Miley Cyrus and Nick Jonas together sing the first verse , " A word ’ s just a word till you mean what you say . " Then the two sing the first chorus together . Demi Lovato and Joe Jonas then sing main lines of the second verse with the other group ( Miley Cyrus and Nick Jonas ) singing , " If we take the chances to change circumstances . " Then , Selena Gomez and Kevin Jonas also join in the second chorus and sing the third verse . For the rest of the song the six of them sing . The overall theme and message of the song is to encourage to pass on the environmental pledge ; this can be heavily interpreted from the lines : " Just one spark starts a fire . "
