On the poem extract below I noticed the following technique and it sounded really familiar, reminding me of punk rock songs and some strong man speeches (I know this is super vague, if I remember any examples I'll link them in the comments). This technique consists of a metric progression of long verses to short verses culminating with a one or two syllable verse, which happens from verses 1 to 5 below, then this is followed by same metric length verses with Anaphoras, in this case it's an anaphora with "the". Does anyone know if this has a name?
1 Pretty women wonder where my secret lies.
2 I’m not cute or built to suit a fashion model’s size
3 But when I start to tell them,
4 They think I’m telling lies.
5 I say,
6 It’s in the reach of my arms,
7 The span of my hips,
8 The stride of my step,
-- "Phenomenal Woman" by Maya Angelou
