The guitar provided consolation for Africa Americans in the nineteenth century

In the nineteenth century, several million Africans were transported to America to work as slaves on plantations in the south of the country. They expressed their desire to play music, but plantation owners thought that drums might be used as some form of communication, and banned all percussion instruments. Yet they allowed stringed instruments, and African Americans turned to the guitar as a way to seek solace. Guitars became extremely popular amongst these African Americans, and developed to such an extent that jazz and pop music became one of the most popular forms of music around the world-transcending racial and cultural barriers.
