Poets talk about the music of a line. rhythmn, tone, tempo,pitch which suggests right away there is something ineffable about poetry, something that is happening on the line and between the lines.
Like music poetry has a powerful effect on our system, an effect that cannot always be articulated.
The tone and rhythm through the syllable and alliteration help rhythm and pace. quick, slow–how do the words help. Repetition of a word or phrase- can be very dramatic to make a point and also helps to escalate the feeling. Is there understatement or overstatement.
Variety of tempos–staccato, silences, pauses.
feeling spaces between the words.
Poetry expresses the inexpressible.
