Poetry

The article, "Philosophy of Music" stated that poetry was excluded from the definition of music. Yet, poetry's beauty lies in its meaning as well as the procession of each syllable sound. What differs poetry from any other written paragraph is its expression, metaphoric language, musicality (in my opinion). Syllables have soft and hard sounds and well as sharp, dull, tinny, dark, bright, etc. sounds. This as well as the use of intonation and inflection when reading poetry gives the words melodic contour in a sense. Rhythm/meter is also a tool used in poetry and gives the poem its shape and temporal characteristics. Finally, poems also use dynamics, emphasizing certain words and phrases, stressing importance, or simply used to illustrate emotion.

Question: Since poetry can have melodic contour, rhythm/meter, and dynamics what does poetry lack, that makes it unqualified to be considered music?
