The Chisungu Richards observed unfolded over roughly a month, led entirely by senior women, the nacimbusa, who staged a long sequence of songs, dances and formal actions built around mbusa, modelled clay or found objects each carrying a specific lesson about marriage, sexuality, household management or correct conduct toward in-laws. The initiate, largely silent through much of the proceedings, was walked through the objects and their associated songs in a fixed order, absorbing instruction less through direct explanation than through repeated symbolic action she was expected to come to understand over the course of the rite.
The ceremony marked its initiate as ready for marriage as much as it marked biological puberty, and its timing in a girl's life was tied to approaching marriage arrangements as often as to first menstruation itself. Richards' study is still cited as one of the clearest ethnographic records of how an initiation's formal symbolism, the specific objects, songs and gestures used, can carry a curriculum of practical and moral instruction without a single word of direct verbal teaching, and it remains the primary documented account of the rite's classical form. Later observers, including researchers revisiting Bemba communities well after Richards, have found the mbusa objects and their associated songs still recognised even where a shortened ceremony no longer performs the full original sequence, evidence of how durable the symbolic curriculum proved once it had been set.
