What figurative language element does Bob Kaufman use when he repeats the word raga at the beginning of these lines from his poem "Unanimity Has Been Achieved, Not a Dot Less for Its Accidentalness"?

Raga of the drum, the drum the drum the drum the drum, the
heartbeat
Raga of the hold, raga of the fold, raga of the root, raga of the crest
raga before coming,
Raga of lip, raga of brass, raga of ultimate come with yesterday, raga
of a parched tongue-walked lip, raga of yellow, raga of mellow,
raga of new, raga of old, raga of blue, raga of gold, raga of air
spinning into itself,
