Love this poem. Some of my suggestions for the attitude/tone are reflective, calm and thoughtful, inquisitive and hopeful and even some sadness.
The mood is mostly upbeat. It is also very calming, in the background, there are some girls singing a smooth melody! What I mean by upbeat is that the song use has good instruments to get a good rhythm. While listening to the song you would most likely feel like you would want to move around. It is not the type of song to make you want to "Do the Harlem Shake". The song is also particularly old.
