It's done by imagery and by assonance (the fortuitous river-names with their clustered consonants are helpful), by polysyllabic words ("vegetable", that inspired adjective) and reference to specific quantities, but above all by the close-knit logical coherence within each section and across the whole poem.
Tai Dam has 19 initial consonants and seven final consonants and three cluster consonants (i.e., kw-, khw-, and ).
If you want to make a very tense, rhythmic, wacky, or harsh sounding language like arabic or German, use tense vowels such as ɪ, æ, ʊ, and ai and try to cluster consonants as much as possible.

There's a diversity of vowel sounds and a choice cluster of consonants in the lovely phrase "a thousand blended notes".
Everywhere else, the result is a confusing fudge of strange clusters of consonants, vowels and diacritical marks.
But Mr. Bush also, in the same forum, mispronounced "obfuscate," even though he was following his habit of edging up slowly to multisyllable clusters of consonants, as if pondering dangerous potholes on his oratorical highway.
