Every macrosegment includes at least two PLs, one at the end and one at the center; if there is a pendant, there is an additional PL at the beginning, and there may be a fourth somewhere between the beginning and the center.
- Hockett (1958), Pag. 39

Every normal utterance in the variety of English […] consists of one or more ‘macrosegments’.
- Hockett (1958), Pag. 59

The stretch of material spoken with a single intonation is called a ‘macrosegment’. We may freely speak either of the center of an intonation or of the center of a macrosegment. [...] Every macrosegment ends with a TC, which therefore automatically marks the boundary between successive macrosegments in a single utterance [...].
