What are some poetic devices in the poem "Good Times" by Lucille Clifton?

"Good Times" is a short poem in which Lucille Clifton
describes some of the simple pleasures of poor African-Americans in the middle part of
the 20th century.

The poem consists of two stanzas, each
containing eight lines.  Most of the lines contain between 5 and 7 syllables.  The
exception to this is the last 2 lines of each stanza, which are a
refrain:

good
times
good times

In
addition to the refrain, Clifton also uses repetition, or anaphora, in the second
stanza:

and
dancing in the kitchen
and singing in the
kitchen

The poem's images are
of simple pleasures at home.  This is enhanced by language that is simple and at times
colloquial, such as, "the lights is back on," and "they is good times."
