I just wrote my dissertation on this topic. I was primarily looking at Pacific Islanders' sea music. I recommend a book, published in 1888, by Laura Alexandrine Smith, titled "Music of the Waters." She collected chanteys and sea songs from all over the world, including China, Malaysia, Japan, Tonga, New Zealand, the Middle East and from many countries of Europe. It's expensive to buy, and hard to find, since it has never been reprinted, but some libraries have it, especially universities.
