Henry Wadsworth Longfellow

Keeping this in consideration, what is the poem the arrow and the song about?

This poem talks about someone shooting an arrow and losing it, and then they sing a song and the song disappears but later find it in a friend. This poem theme is based around the fact that words are unbroken. When the person in the poem shoots the arrow it is like when we lash out at someone or say unkind words.
