All one has to do is to imagine a score with identical silences between notes, as in a popular song, to see that this is so. I am not able to carry this further without becoming too abstract and diffuse, and there is not much point anyhow in claiming that they are. A better question to ask is what correspondences and connections are there between the intentions and effects of poetry and the intentions and effects of music, and how does the nature of their resources affect this. Not all kinds of poetry and music, naturally. . . . They both aim for the heart.
Music travels straight to it and wrenches it.
The effect is instant. Not so poetry. Its lyrical impulse is tempered and modified at the very start by the nature of language, which places cognitive expectations on itself. To get to the heart, therefore, the lyrical impulse has to sneak around them by a devious and complex route of word associations and timbres and cadence. Indirection is its very nature.
