A poem may be of only four words, and yet those four words may contain enough suggestion for four pages of music; but to found a song on those four words would be impossible.

For this reason the paramount value of the poem is that of its suggestion in the field of instrumental music, where a single line may be elaborated upon....
To me, in this respect, the poem holds its highest value of suggestion....

A short poem would take a lifetime to express; to do it in as many bars of music is impossible.

The words clash with the music, they fail to carry the full suggestion of the poem ...
"Many poems contain syllables ending with _e_ or other letters not good to sing.

Some exceptionally beautiful poems possess this shortcoming, and, again, words that prove insurmountable obstacles.
