“Identity and communication
In order to interact with each other on the voyage, slaves created a communication system unbeknownst to Europeans: They would construct choruses on the passages using their voices, bodies, and ships themselves; the hollow design of the ships allowed slaves to use them as percussive instruments and to amplify their songs. This combination of "instruments" was both a way for slaves to communicate as well as create a new identity since slavers attempted to strip them of that. Although most slaves were from various regions around Africa, their situation allowed them to come together and create a new culture and identity aboard the ships with a common language and method of communication:
[C]all and response soundings allowed men and women speaking different languages to communicate about the conditions of their captivity. In fact, on board the Hubridas, what began as murmurs and morphed into song erupted before long into the shouts and cries of coordinated revolt.
This communication was a direct subversion of European authority and allowed slaves to have a form of power and identity otherwise prohibited. Furthermore, such organization and coming together enabled revolts and uprisings to actually be coordinated and successful at times.” — 1) https://en.wikipedia.org/wiki/Middle_Passage#cite_ref-26
