  The human voice is the original instrument for making music. A person brings their voice wherever they go and they bring the songs of their homelands despite the conditions of their arrival. A piano was not necessary. Africans arriving in the Americas were able to make drums, reed flutes and stringed instruments, precursors of the modern banjo for musical and dance performances (bamboulas and banzas) at Congo Square in New Orleans by the first quarter of the 19th century.   Wikipedia is just full of false, unreferenced, biased BS. You can't believe hardly anything you read on there. People think it is just the word of God these days, anyone who wants to can edit that site to their little heart's content.
