Enumeration in simple sentences is represented by a number of homogeneous parts. Each of them is pronounced as a separate intonation group.
Low Rise is usually used in the non final intonation segment showing that there is more to be said, that enumeration will be continued; the final intonation segment is represented by Low Fall, thus showing completeness, e.g.:
I `bought some `socks, `shirts and ֽties.
All he `does is `sleep, `eat and ֽplay.
