This item is not in the library — it is a part of: A. Fleugelman (ed.), The New Games Book.
Presented as a traditional free-form activity of hitting the ground with sticks or sticks to each other; in The New Games Book text Lummi sticks are somewhat conflated with Ti Rakau of the Maori. The activity is based on rhythm and produces sounds, but unfortunately, the interactive process is extremely open and not refined into the game. Also, traditional patterns of sticking in both Lummi and Ti Rakau seem to usually be strictly defined, too constrained to be a music game in our understanding (similarly to most of the world's clapping games; "citation needed").
As for the topic of the "traditional" conflation see:
